Posting Order?

I know i am not a group leader or anything. But i wanted to ask about this. For big group threads, like for example the class ones and open to everyone. Maybe we could have a posting order, so that way no one can get left behind and everyone will have a chance to post? It may not bother some but i think in a team-playing roleplay a posting order may be needed. I know it may seem like a big waiting game but i think it could really help to make people feel welcome
