It's a problem that plagues online games.
In the two years that I've been playing PBP's and PBeM's, nearly a dozen games that I've been a part of fell apart shortly after they started.
It's usually starts with one or two people slowing down their post rate, before stopping completely... Pretty soon no one in the game posts at all. The only real solution (other than ditching the game completely) is to exclude or replace the slow players, and keep everyone else moving on.
The problem I, personally, have with my games slowing down, is when my players get to a point in the game, where there is a decision to be made with no particularly clear solution. I like my players to think for themselves, and hate railroading them unnecessarily. In the games that I GM online, all those that have slowed down and failed, seemed to be because the players refused to take any initiative of their own, and I refused to lead them by the nose.
I think that's what's happening to a small degree here. Sit around twiddling your thumbs long enough, and I'll throw a "kick in the pants" your way... Like an enormous poisonous snake hiding in the middle of a river.
I take the same stand that Piratecat does with the D&D Iconics... I have no qualms about target inactive characters. Slow characters may find themselves kicked in the pants while the others move on. Also, I have no qualms about docking them XP.
That said, the only characters I am worried about lately are Rorworr and Set. You two guys haven't been posting much, unless I send you email reminders. Do you guys need a kick in the pants? Should I find other players?
If any of you run into temporary problems posting, or foresee temporary problems posting, then please drop me a line by posting a message here, or emailing me... I doesn't take that long. I won't get mad, if I'm expecting you to not post.
The player who was going to play Kelko has backed out, so I still need a new player for him. For now, he's an NPC, and will be played as such... In other words, he will only take rather obvious actions, unless explicitly asked by the other characters.
Also, someone has stepped forward to play Valara. I should be able to introduce her soon.
