Hmmm! I do the same as Flecc, so I never take notice of what section things are in.
I like it that things get mixed up because it gives a sort of cross-fertilisation of ideas. Also it could get a bit awkward in some circumstances. Say a guy posts in the electric bike section that he's struggling with his unpowered bike, so he wants some ideas for which electric bike to get. It would be bad if one couldn't suggest that he tried a conversion kit because you could only post that in the kits section, or you could get the vice versa situation.
Thats not really an issue thou because its related
Off the top of my head , Its people who post stuff in the classifieds when there not selling anything
Theres others in site announcements feedback and support with people asking about ebike rental ,battery connection issues,replacement sensors etc which are clearly nothing to do with the mechanics of the site which is what its for
Surely without some order the forum would become unuseable especially searching for info which is how many people end up here in the first place
I must admit i do have ocd so everything has a place and im very methodical with what i do for a living because i have to be which also doesnt help
But still how hard is it to look at the sections in the forum and put your posts in the right area , it doesnt take a genius to figure it out .
