The best way to apply for a character is to email scribuscaballus (at) yahoo (dot) com. The equestriandawn (at) gmail (dot) com address is a shared account for the administrators..
If you're having specific in-game troubles, you can @mail or @page a listed Wizard. There's a signpost in Ponyville Town Square (look Wizard Directory) if you don't know who to contact.
Apologies for any confusion.
