Just a fair warning if you're searching for this kind of tool... This is right up there with spam bots , adware, and similar questionable marketing tools. Sure there's legit products out there but you're going to run into a whole lot of viral or otherwise funky sites while searching. Be careful with your computer :) As for the actual game you're setting up, it wouldn't be too out of the question to just use the chat bar within a Roll20 campaign for PbP games. You just need to get the players to keep it to in-game chat only, and use the campaign forum's for more casual conversations. That allows you to roll in-game with your "posts".
