Second characters are allowed under some conditions. The guidelines are simple:
The Wizzen must be notified of second and multiple characters. Having second characters is not appreciated; however, if a good reason for having them is given, you may be allowed to keep them. We the Wizzen reserve the right to decide who gets to keep second characters, and which ones will be deleted.
Extra characters may NOT be used for quota purposes, unless allowed specificly by the Wizzen (you must ask for permission, and have a very good reason for needing it, keeping in mind that needing it for more quota is NOT acceptable) - use $projects when possible.
Second characters being used for malicious purposes will be deleted, and the primary character will receive the due punishment.
