Hmm! This would be a really cool bingo fest – actually, it might be really cool to do a set of, say, three bingo fests, one after another: one for worldbuilding, one for culturebuilding, one for characterbuilding or castbuilding.

What does running a fest entail? I'm pretty overcommitted at the moment and wary of adding anything else on, even late in the year, but it's definitely something I'd be interested in once life settles down a little.
