Go to the RTB forums, the members there are on probation basically :/
The bulk of RTB and blockland beta discussion goes on here (minus the actual RTB beta testing which is hidden away in the RTB forums) and then we fill in the RTB forums later when we remember they exist. All of the cool stuff (arch bricks, doors, obj to brick coverter, heightmap to build converter, etc) either gets posted here first or gets posted here exclusively. The RTB forums is just a bunch of forum veterans and people banned from these forums trying to one up each other by seeing who can make the most menial forum reports and still provoke moderation. If you're into that sort of thing I guess you could join.
Oops did I say that out loud?
