If you only read the Rage of Bahamut Unofficial Wiki website, there is no more information collected about you than is normally collected by web sites in general in their server logs.
If you contribute to the Rage of Bahamut Unofficial Wiki website, you are publishing every word and/or image(s) you post publicly. If you write something, assume that it will be kept forever. This includes articles, user pages and talk pages. Some limited exceptions are described below.
Publishing on the wiki and public data
Simply visiting the web site does not expose your identity publicly.
When you edit any page in the wiki, you are publishing a document. This is a public act, and you are identified publicly with that edit as its author whether by User name or IP address.
When you publish a page in the Rage of Bahamut Unofficial Wiki website, you may be logged in or not.
If you are logged in, you will be identified by your User name. This may be your real name if you so choose, or you may choose to publish under a pseudonym, whatever user name you selected when you created your account.
If you have not logged in, you will be identified by your network IP address. This is a series of four numbers which identifies the internet address from which you are contacting the wiki. Depending on your connection, this number may be traceable only to a large internet service provider, or specifically to your school, place of business, or home. It may be possible that the origin of this IP address could be used in conjunction with any interests you express implicitly or explicitly by editing articles to identify you even by private individuals.
It may be either difficult or easy for a motivated individual to connect your network IP address with your real-life identity. Therefore if you are very concerned about privacy, you may wish to log in and publish under a pseudonym. When using a pseudonym, your IP address will not be available to the public, but it will be stored on the wiki servers for a relatively short amount of time. Thus it will be available to developers and may be released under certain circumstances (see below).
If you use a company mail server from home or telecommute and use a DSL or cable internet connection, it is likely to be very easy for your employer to identify your IP address and find all of your IP based Rage of Bahamut Unofficial Wiki website contributions. Using a user name is a better way of preserving your privacy in this situation. However, remember to disconnect yourself after using a pseudonym to avoid allowing others to use your identity.
The wiki will set a temporary session cookie (PHPSESSID) whenever you visit the site. If you do not intend to ever log in, you may deny this cookie, but you cannot log in without it. It will be deleted when you close your browser session.
More cookies may be set when you log in, to avoid typing in your user name (or optionally password) on your next visit. These last up to 30 days. You may clear these cookies after use if you are using a public machine and don't wish to expose your username to future users of the machine. (If so, clear the browser cache as well.)
Many aspects of the Rage of Bahamut Unofficial Wiki website community interactions depend on the reputation and respect that is built up through a history of valued contributions. User passwords are the only guarantee of the integrity of a user's edit history. All users are encouraged to select strong passwords and to never share them. No one shall knowingly expose the password of another user to public release either directly or indirectly.
You may provide your e-mail address in your Preferences. This allows other logged-in users may send email to you through the wiki (unless you disable this in your preferences). Your address will not be revealed to them unless you respond, or possibly if the email bounces. The email address may be used by the Wikimedia Foundation to communicate with users on a wider scale.
If you do not provide an email address, you will not be able to reset your password if you forget it. However, you may contact one of Wikimedia developer to enter a new mail address in your preferences.
You can remove your email address from your preferences at any time to prevent it being used.
Data on users, such as the times at which they edited and the number of edits they have made are publicly available via "user contributions" lists, and occasionally in aggregated forms published by other users.
Removal of user accounts
Once created, user accounts can not be removed. It may be possible for a developer to change the username on an account, but you will need to request this yourself. The Rage of Bahamut Wiki website does not guarantee that a name will be changed on request. Contact Ezo, Mindsonic, or one of the other administrators of the site for further details.
Whether specific user information is deleted is dependant on the deletion policies of the project that contains the information.
Deletion of content
Deleting text from the Rage of Bahamut Unofficial Wiki website does not really delete them. In normal articles, anyone can look at a previous version and see what was there. If an article is "deleted", any sysop/administrator, meaning almost anyone trusted not to abuse the deletion capability, can see what was deleted. Only a developer can permanently delete information from the Rage of Bahamut Unofficial Wiki website and there is no guarantee this will happen except in response to legal action.
