I joined this game because it was explicitly stated in the OP of the recruiting thread that you wanted daily posts. (which I thought was pretty optimistic). I'm fine with a post every couple of days. I actually enjoy pbp a lot so am often checking the thread to see if it's moving. If I'm not going to be around for a few days, I usually post it OOC. (like this weekend I'm camping again!)
So far, I think things are good on the DMing side. I'm not sure what else you could do since you're responding IC as soon as people post. One thing I've done in a PBP I've run is, if there's an agreed-upon posting speed and people don't post, the DM just moves on regardless. In combat, that would be having people go on the defensive. Out of combat, that just means they just follow the group. I'm not sure it will work in this style of game, though.
To touch on
@Necropolitan point of skills, I'm of two minds: I don't often like to roll a dice if my In-character action is good enough to succeed at the task at hand. On the other hand, in a pbp, it takes time to wait for the dm to call for a roll or whatever so, in other games I play, if I think a roll might get called, I just put rolls in for the dm to take or leave. In this game I haven't been rolling at all because, overall, things have been going smoothly (I think). I currently have a goal but I haven't had a chance to enact it yet.
I'm also finding that doing OOC planning is difficult in this game because:
1. We are supposed to have secrets (I haven't really been narrating 'inner-thoughts' very much)
2. OOC planning is slow. I'm not opposed to it but if people aren't posting IC, they're probably not posting OOC.
I don't mind doing it, though. Orris has been trying to recruit a 'guide' since the very first post. It's why he knocked on the door.
I think our goals (as a group) are:
1. Figure out where we are
2. Figure out what's going on
3. Go to the castle/mansion
I kind of feel we are investigating 1 and 2 on our way to 3.
