Being GM sounds like a lot of work, not to mention I just started using the RP forum. I'll think about it, being GM that is.
As for the idea: it'd be perfect! I recently played The Walking Dead Ep. 1 and all the decisions you make truly does come with a cost. The GM would calculate all the actions the RPs in the thread do: surviving, interacting, etc. And, if possible, the GM can be capable to bringing in events (such as a sudden zombie attack, or, in a last resort, give someone the choice to save a teammate or have someone killed). This may sound sudden but, in my opinion (and probably others), there should be a "The Walking Dead" RP thread.

Yog: Exodis, your manner of speech and the way you conduct yourself is beginning to evolve to the point where I'm starting to like you.
