First post is up in the thread:
Return to Olaj
Generally the way I like to run things is to post a situation, let everyone tell me what they're going to do, and then I'll recap the action that everyone has taken (and resolve what needs to be resolved). I'll usually end a post with a "The Situation" OOC just so that everyone knows what's going on.
Even if your action is to essentially do nothing go ahead and post something. If the situation is one where I need an action form everyone I will generally wait 48 hours or so for you to get something posted (not counting weekends - those generally tend to be pretty slow around here). If you haven't posted in that time I will move things along and either assume your character is following along with the others or take an action for you (which may or may not be to your character's benefit, depending on my mood. :-)).
