Great idea for a site, Simon. I think this could be really useful and fun.
But I want to make a few requests. I'm not familiar with Vanilla,so not all of these are going to be realistic or easy but hey, ideas, right?
Some kind of message stickied at the top explaining the reason the forum exists. Yes, there's that "First Post" thread, which is basically cool but having something called "What is Snail's Pace for?" would be really neato.
Vanilla uses a standard icon thing, looks like a black square with two green leaves on it. Story games and Knife Fight use the same software and therefore use the same icon, making it slightly harder for me to tell which one's in which tab. If the icon can be changed, that would be ace. I'm sure there's a fairly big crossover between here and SG, and a fair number of us using Firefox the same way I do.
I'd like to see playing cards supported in the same way dice are. That'd kick backside.
I'm sure other people will chime in with their own requests and whines ;^)
