I don't believe there currently are, but there have been some in the past! I'm in no place to run one myself - though I'd love to - but you can always make one if you know how to DM.
The only thing I can think of right now is how @RaidenCheese runs his roleplays - he often rolls to see what would happen during his roleplays, though the one he does that for isn't active right now.
Tons of cowering! Plus your name in the summer programme. A custom-designed banner. A cabin at Camp Half-Blood. Two shrines. I'll even throw in a Kymopoleia action figure. — Rick Riordan, The Blood of Olympus
