Sometimes they aren't. Links die, threads get unstuck, that sort of thing.
Something similar to this
(subforum over on customcockers) would be cool, I think. Maybe even do it similar to the reviews section here, considering the fact that CC has 41 articles for really only 1 gun. Would make it easier to add user-generated content somewhere easy to find, as opposed to having to hope something gets stickied or added to an existing sticky. Some subforums are better than others about that sort of thing, too. The high-traffic ones seem to be pretty good, the others kinda fall by the wayside.
