I'm afraid I have bad news.
It looks like I'm going to have to decline your invitation. Having spent a week thinking about it, I just don't feel I would have the capacity to add a second PbP game and be able to participate at a level I would feel was adequate. Since it seems you have already had numerous problems with people joining and then failing to participate, I don't want to do the same to you again. I'd prefer to excercise moderation and continue to build on my reputation as a reliable gamer for future PbPs I might join.
This looks like a fun game, and I tried every way I could to justify joining it to myself. I'll certainly keep an eye on this one, and perhaps if a chance comes in the future, I could jump in.
Thanks for considering me. I do consider it a compliment.
