It sounds like a good idea, but a bit useless at the same time?
Users can simple use the PMing system to communicate and do 1x1 Roleplays already, although it can be hard to keep track of if you get messages every day.
Never the less, it's a good idea, it'd be nice to see some more opinions on this.
I think this is kind of lovely. Though I'm not sure how long these 1x1 forum RP's would last without them dying out quickly in all honesty. Sometimes you need more than two people to keep a roleplay interesting. Though, I don't see that being a problem with the really creative users on FH. This one is a bit of a tough one to figure out whether or not it'll work in all honesty.
