Not the kicad forum specifically but I've been to other forums that use the same software (discourse) and I agree it's better than phpbb (used here). There was once an attempt to move to that software here too, it seems migrating is not so trivial to do though and some folk have actually expressed that they prefer this forum, so in the end it didn't happen. Hopefully we'll get there some day.
weird, try fully clearing all cache and session data for freecadweb.org from your browser, I can't remember how exactly this is done but it shouldn't be too hard to find on google.
Regarding the icon, 've seen the issue you submitted to yaru theme, they indeed have welcoming people!
