I’ll respond but without my moderator hat on for the sake of clarity.
When I moved to the area not far off 16 years ago, the only local source of information I could find was the .com site. At the time I found it hugely useful, and it no doubt still holds some interesting information in it’s archives.
I once spent a considerable time detailing a list of all parks in the area (similar to the one I did here) and it got deleted for no reason - though in contrast to others did get a response when I asked why.
It’s not my place to say why, but that site effectively lost most of its active members. Some moved here, and some will have moved to facebook groups like the popular se23mums which I am also part of.
I’ve no doubt that from a user experience across multiple devices this is one of the best forums, not just locally, to use. I think there is an underestimation of the amount of work that has gone in to developing that in the first place, and to continually improve and maintain it.
You and the poster above are correct - the platform should in effect merely facilitate members to help with various projects - and I believe in that it succeeds. The forum cannot generate or push what people do - only people can do that - but the forum has been well designed, in my opinion to allow that.
In a utopia, you’d hopefully not need moderators and the site could self-moderate. At times, the site almost does, at others it needs lots if intervention.
I’ve probably strayed a little into speaking as a mod, apologies. But for clarity this is just my opinion.
