I believed the rules and regulation for this one is on the site . So just check it
I have checked the stake forum site and the rules for this seem to be coming soon.
I've made 12 high quality posts (actually asking or responding to questions, not posting in their "counting" threads) and racked up a whopping 797 satoshis. So while this may become something right now it isn't.
I do think it's a good idea to try and build up a forum given bitcointalk's strong position. I'm not sure why stake and primedice needed different forums though. Anyway, right now I'd say watch this for future developments rather than taking it at face value like I did and start posting unless you are already a fan of stake or primedice (which I sort of am, so all good).
