The character approvers have to do that in their spare time, and on a volunteer basis, so real life willing they try to get them done as quickly as possible. Approval time is really hard to generalize because each character submission is so different. My suggestion is to keep your eye on the boards and when they respond to you, make any changes/corrections they need done (if any at all!) so that your character fits into the world as we know it. Hopefully we'll get you playing with us as soon as possible. Welcome to Layo!
