1. What part of the forums do you like the most?
I'll regularly look to see if there's anything new in the 'News' and 'Sports' sections, plus anything else that catches my eye
2. What part of the forums do you like the least?
I couldn't single out something, if it doesn't really interest me, I won't bother with it. Just went back to add this … when typing in lengthy posts (like this one) the text box annoyingly jumps and scrolls all over the place, probably my setting?? Correction, its not just annoying it's bloody infuriating 
3. Are the forums easy to navigate?
I would have to say no, but then again I find that with similar message board/forums sites. I did notice recently that there has been a 'tidy' up of the sections which is an improvement. Is there a way of jumping to your favourite sections? I mean something that can be saved under your ID, rather than saving a section in you browser 'favourites'
4&5 I've not put any thought as to what should be consolidated/condensed. I suppose when I get used to where something is, I don't want it moved ;D
General thoughts ... I guess the vast majority of people using the site are only here for the files. So....
a) they have to be more aware that the forums exist
b) there has to be relevent content (to them) that would entice them to the forums and keep them coming back
(a) is relatively easy to do, as shiggy suggested, having a link in torrent pages to a relevent forum section would be a good idea for starters. (b) Keeping people coming back is more tricky. One obvious carrot would be some sort of seed bonus reward for a number of posts, but the downside would be potentially spurious posts to bump up your bonus.
It's difficult to know what additional interests should be added, without doing a lengthy survey. After a post in the Sports section by leatherbear a few months ago, asking if anyone wanted to start any other sports themed subsections, I have toying many times about requesting a rugby one. I don't doubt that rugby has a big gay following for many reasons, but the thought of putting the time & effort into something (and not just in a half-arsed way) and there being little or no interest, is off putting. I guess it's a chicken and egg scenario.
It would be great to see more involvement on the forums, while maintaining the troll-free, pleasant atmosphere on them (which is pretty astonishing considering the abuse that's posted on even the more innocuously themed message boards around :D)
