I don’t know what tools are available to the mods... but a good start to an automotive section could be flicking through the subject line of the last 30 days new threads.
Agree about too many sections, that was my thought about eliminating those sections with low posting populations. Perhaps 10% or more could be bumped around (leaving the language sections alone).
And not sure what’s involved, but maybe i’m a bit too opinionated to be a mod!
