>.> While being able to post regularly is great, GMing is a bit of a different battle... and it also really doesn't do much to make sure other people are posting, nor does it ensure that you'd be keeping an eye on any problematic interactions that could create kinks in the activity flow...
Also, while Luma's been doing an awesome job of keeping track of characters and races and stuff, I haven't instructed them at all on the usual way that I keep track of posting groups. I have no idea if they've been keeping an eye on activity flow at all.
That being said, the RP is sandbox-y enough (not to mention active enough) that it seems to be doing fairly well without it, but... yeah, not really the same thing.
