You're doing fine, Froggy. GMing by post can be a little more involved than tabletop. The only real difference is pacing and giving your players time to act and interact. A 5 minute conversation may take a week to work through in PBP and it requires a bit more patience on everyone's part. It's not a skill that comes quickly to GM's who have never done it before, but not hard to adapt to. It's the primary reason why I don't GM here.; I don't have the patience to pace things properly. I either give way too much, or way too little in what's happening at the moment.
