Sorry, but I disagree. There are several problems with introducing subsets of the current fora. The most obvious is where does it stop? Soon we'll have separate fora for micolighters under the age of 32, anyone who flies purple aeroplanes (sorry Stik
) etc etc. The problem of where precisely your question on flying a purple microlight when you're 31 would then arise. Also, many people may not venture out of their own narrow forum and so not read the extremely useful advice that might be relevant.
AND ... there would always be someone who would complain his/her suggestion for a new forum was ignored, while someone else's was taken up.
