Applications are a three step process:
First, you send an email to [email protected]. It should include the name of the char you want and a brief description of your concept of the character. One or two paragraphs is plenty; this isn't an essay contest.
Second, the gamemaster gives you the char and your password. You enter the newbie zone of the MUX and fill out your +finger and @desc. Then you build the char according to the rules noted above ans submit the char to the GM.
Third, the GM goes over the char and the two of you settle it to his satisfaction. He then sets you approved and you begin play.
Until the MUX has its own site, see tempsite for details.
