Your name is also a potentially valid WikiWord when used within a topic. However the home pages of registered users on this site are stored in the Main web. When you sign your username in a topic, prefix it with Main. (including the dot). That is, write Main.TWikiGuest to link to TWikiGuest, your personal home page in the Main web. For convenience, your signature is also provided for copying and pasting when editing a topic.

Though rarely used in common practice, you can use the special %USERSWEB% variable prefix for user names, for example, %USERSWEB%.TWikiGuest.
