[Vortar the Mad]

Sometimes a DM doesnt have the ending "planned", he/she is waiting to see what the group does to decide where the event goes from a certain spot.

So emote, talk IC, figure things out. Standing in one spot shooting tells to each other about "Did the DM fall asleep?" is not the best option, ever.

Also...sometimes the dm is not with the pary but in another location setting up encounters, helping other players etc...so it is helpful while in an event to speak in the "party" channel. This allows the dm to easily see what is going on with the party and award xp accordingly for good roleplay.
