Not sure how to install it, though, so I'll leave it to you, Beige. That way it's not my fault if something breaks.

This should provide something like we had on the old free forum, where we included a brief welcome message and a call to action for new members with a link to the "Introductions and Reacquainting" thread. The announcement can be updated whenever there's an event of some description -- perhaps an organised mission, a podcast or a game night -- but the most important thing is the welcome message and link to the Introductions thread, I think, otherwise it could be daunting for new members to know where to start.
