Just a quick suggestion and I will try to make a video myself as I will be able to record soon, but basically we should create short videos showing off servers/gamemodes, very similar to how Filipe made his Speedkart gamemode. Why you ask? Well I really want BL to get on greenlight and we need to show off more gameplay, the best way is by video. Badspot will most likely add these videos to the greenlight page like he did with Filipe's Speedkart.
A couple of ideas for trailers
Murder Mystery
Jail RP
Freebuild/Community Build/City RP (this is a big one since BL is about building)
Heed's TDM (another big one)
