All Merlin, No Waiting

[merrily]

Hey dudes, I decided I was tired of waiting for someone else to create an sga_noticeboard for Merlin, and did it myself.

Please pimp merlin_bulletin widely! Works the same as sga_noticeboard, but I've suspended the rules about comms for the time being, since Merlin is new and fresh, and I suspect there are lots of worthy communities which don't have ten members yet.
