I frequent 2 motor forums - one is like this (was) and is "general" to all irrespective of model, location etc.
Lots of postings, lots of help, banter, etc. just like here.
The other is split into various "sections" with the result that posters tend to post only on "their" section and it's ended up with just a few regulars in each. The "general" section is not used as much and overall I think the forum suffers because of this.
The thing that holds us all together is beekeeping not location.
