Pretty much this entire 'main' area of the guild is for open role play. Just be sure to label what kind of rp you're in. For those that aren't savy to this system:

The title should read either [PRP] (private role play), [ORP] (open role play), [PD] (play date), [SRP] (self role play).

Little Explanation:

PRP:
Private RP's are arranged between 2+ people. They don't want anyone to interfere uninvited with the role play going on. Unless you're invited please refrain from posting. You're free to read unless the first poster has a disclaimer on the top. That happens rarely so no worries.

ORP:
Open rp's are open to everyone! The player starting the open RP may want to meet new children, have a large game between several children, etc. If the title says "ORP" feel free to jump right in, though the starter of the thread might insist on a posting order.

PD:
Playdates are normally arranged between parents. The children have a set meeting place, like one of their homes or a park. Normally it's between only two children.

SRP:
Self rp's are pretty much one player writing out a situation for their students. These are normally kept in journals but some people prefer to post them out in public so other players can see what's going on.
