I have never run a PbP, though I am an experience DM 25+ years. I have always wanted to do this, but haven't had the push yet. I have lurked in a few games, and I see that there are some fairly standard etiquette rules, as well as some "house" PbP rules.
If someone would consider co-GMing (helping with the meta-aspect of PbP GMing) I would love to give it a go.
If you run a game RangerWickett, let me know, I would like to play in one. I would be a rookie, though my writing and RP skills are fairly decent.
