How about have a category for each bit of kit as you do, then sub categories for individual manufactures? i.e. Dye/Proto, Invert, Eclipse...similar to the PBnation? in each sub category people can post there issues and have PDF. manuals ect. stickied?
maybe its just me but i dont like threads which every 3rd post says exactly the same thing for 20+ pages, then gets digged up again by someone a month later and and the process repeats.
