Merlin:FAQ

What does the 'citation needed' tag mean? What does "purge" mean, and what does it do? Is there a wrong way to use the Message Wall?
 * The link "citation needed", means that the statement tied with it hasn't been confirmed yet, and a source is needed!
 * You'll notice that clicking the time and date in the top bar will perform a "purge". This means clearing the cache of your browser (Google Chrome, Firefox, Internet Explorer, and Safari are all browsers). Purge is useful when you want to see changes made to the Wiki immediately, but you aren't seeing them. Purging is useful mainly for more advanced users.
 * See the Wikia article on Purge for full information.
 * There is generally no wrong way to use the message wall, as long as you are not swearing or harrassing. You are allowed to use the Message Wall to however the way you please, whether if it is Merlin-related or not.
