Evening!
I think the atmosphere here is terrific, the content very good. The amount of closed threads did initially trouble me, but when you look at some of the other forums which are less gung-ho in thread control, there tends to be a much less informative and friendly ethos. I guess it's for the best.
A few ideas:
1) Too many stickies! Having 6 of 'em plus an announcement sort of defeats the purpose of them in the first place. I don't think the social thread needs to be a sticky, as it's always active anyway. The reminder thread seems a bit pointless too, people read these things but it often won't sink in, especially when the title is not very clear - to someone with limited forum/PD experience, 'What Did I/Should I Take" Threads' may not immediately register as meaning what you intend it too mean, especially the 'should I take bit'.
2) Consistent and, dare I say it, less formatting/highlights. Having certain woods capitalised, and lots of *** looks (to me at least) a bit messy, and doesn't encourage me to read these threads at all! Also I think the 'new' et al, labels in the best of PD thread look a bit (and I mean this in the nicest possible way!) scatty! Also a bracketed (Social Thread) or something besides the funny and random thread name would be helpful!
3) Links to erowid/blueligh/other trip reports that summarise the affects of a compound very well. Maybe at the start of the B&d threads. This sounds time consuming, but I bet if you started a good trip report suggestion thread for a compound every week, a decent list would appear in no time - a lot of posters have already read a lot of trip reports.
I just think reading some experience reports is often the best way to understand a compound, obviously people can do that themselves but there are an awful lot of trip reports about for, say Salvia - I don't think many of these convey a very clear picture though (not surprising).
4) A PD Philosophy Thread. Invariable philosophical ideas get tied up with psychedelic use. There is a whole philosophy forum, but psychedelic linked philosophy topics seem to get discussed very surprisingly little.
