I am running several PbP games, and have discovered that I have a small number of players who are not actively participating in the games (and who haven't told me they'd be away/busy/unable to check in/whatever).
At first, my stance was to leave them wherever they were standing, and essentially treat them as if they were on delay until they checked back in, but this is unfair to the other players (especially when the non-participating player can bump the APL up and affect the difficulty). I could similarly NPC them, but I feel that shouldn't be the case for large portions of the game.
My "common sense" solution would be to not give gp/XP/PP credit for the encounters they were absent for, but that seems somewhat harsh. And, there are also players who are 'participating' by choosing to do nothing at all, sometimes not even entering the building with the rest of the party - what about them? Of course, sometimes there are in-game reasons for this (I'm looking at you, Mr. Paladin asked to break into a place illegally!), but I don't know how I can justify giving a character rewards when they aren't even in the building.
I have flagged the non-participation to the player in some cases, and not (yet) in others. I thought I should have a policy in place before I go much farther.
Precedent? Comment? Opinion?
