Does your game continue when the regularly scheduled time is over? Do you send out emails with what is going on between sessions? Do your players send you emails with how they are reacting? Are there side meetings? Conversations that actually impact in game events? If you do do them, do you warn people that they happen, and can happen? If you don't allow them, is there a reason?
I'm likely going to talk about the ramifications of doing these later on, but for today I'm just curious if you use them.
Personally, I do. I try to limit how much they are used, but whenever there is a time skip in my game there is always the possibility for something minor - but significant - to happen and so I send out an email with what is going to happen over the break, and what NPCs are doing what (provided it is information the PCs would get.) My players, in turn, respond with what they're doing, or trying to do.
In the end it means the game gets more done between sessions, letting us focus on juicy session RP when we have our regularly scheduled sessions. But it's not for everyone.
So, do you do them? Do you not? Why?
