Maybe an additional forum where people can list up coming events or places to visit?
Also, the 'analogue' forum seems a bit of a clumsy name. I realise it's intended to contrast with the 'digital' forum, but personally I'd prefer good old 'film'.
I agree about having a limited number of sub-forums. It's not as if there will be hundreds of messages every day to try and trawl through, so I don't think highly specialised sub-forums are likely to be necessary.
