OK, I'll 'fes up, I use an ad blocker. But in my defence I installed it because of ads on another forum, not here.
I'm probably not the 'typical' user of the forum as I don't spend much time on here. I generally only look at the WIP and under glass sections for cars and 'light commercials' as they are my main interest. So I would personally say there are more than enough sections now. I think it would be difficult to police sections for 'period' builds or level of modifications as it's somewhat subjective. I am a little unsure about the drag racing section in fact, for example I wasn't sure if I should have posted my '37 Chevy build in there. But it didn't get moved, so...
As others have said, a preview button would be nice, sometimes you see you've missed something or want to re-arrange things to make the post clearer.
