I know everyone hasn't answered yet, but it seems like a personal drop-in is more preferred. If anyone prefers something else, let me know! It's still possible to figure something out.
I'll still wait for everyone else to respond, but for the people who have, how do you want it to happen? Would you like to have Merle/someone else appear at some point in your post to recruit them, or an entire post dedicated to the conversation/follow-up? If you want to have it be Merle, let me know, either here or by PM. We'll get to working something out.
Another idea is to have it be Maria - "Vault". She's going to be a secondary character throughout the RP. At the moment she doesn't necessarily have a locked-in personality, so she's up for grabs if anyone wants to use her. If you want more information on her, I can PM you details.
@McHaggis, stop slacking! You can do it! I believe in you! And you're not capable of "half-decent" posts, so don't even try to be humble.
