Okay, so I want to have multiple threads for the action, because the first session in this case is not going to be 'so you're all in a tavern'. Is there any way to do this, have multiple gameplay threads, or am I going to be stuck with a dozen orphan threads that can't be linked to the campaign?
I'm not sure on the technical matters of linking multiple threads. But have you considered using one thread with appropriately labeled spoilers to divide up the action? I've seen that method used before to nice effect.
You can link multiple gameplay threads to a single discussion thread, they'll show up as separate campaigns on your summary page in your header.
That is a seriously sub-optimal decision. I suppose I can understand it, from a technical point of view; less need to track individual threads.
I suppose I'll likely do as you suggest, Rennaivx, instead of tossing out a dozen different threads, especially as time goes on.
