I tried PbP once before and it was an unpleasant experience, but I believe that it was my own doing, unknown expectations, etc.
I would like to try again, if there are any groups forming or established who would be willing to take on a novice at PbP in the CT version (only books I have). Experienced at RPG's and used to play Traveller live, but that was many moons ago.
Be gentle....?
