I would say posting 3 days a week ( or more) and that could include out of character thread post as well. They don't have to be long posts just enough to keep the story moving. I would say I am probably the least prolific as far as individual post length but am lucky enough to be able to post regularly.Define "fairly committed". I might be interested+1 for Elenath.
I will be starting a PbP game soon, using The One Ring 2nd edition. I'd like at least 1 more, ideally 2 more fairly committed players.
