There is now such a mass of content that we rely heavily (and often unsuccessfully) on Search to locate topics or posts of interest. Perhaps General Usage (approaching 10k topics and getting on for 70k posts) would benefit from splitting into separate categories?
Off the top of my head it might make sense to have FH Versions as one level-2 forum (or even be a top level itself) with sub-forums for each version (and even lower for sub-versions?).
Ancestral Sources gets its own forum, but other programs/sites that link in some way (e.g. Parallels or mapping) don’t get collected together, as might be helpful.
There are certain other (perhaps many) focused topics that are clear candidates for grouping too (e.g. Witnesses), but you of all people will be well aware of that.
Thanks for reading.
