Howsabout keeping tabs on the most used sections for a couple of weeks, and ordering them from most to least popular?
And/ or considering a parent & child board system- works well elsewhere.
EG:
Parent forum:
Meeting
Child boards:
Socials & Munches
Dogging meets
LMU

And so on- then if you're a non meeter, you just hit the cafe. A non natterer, the meetings section.
