You know what really, truly, annoys me? Message boards that absolutely require you sign up to use them - or, not even that, they require you to sign up to even look at them. It's simply annoying. I can't tell you the number of times I've wanted to post one solitary message on a board - and find I have to go through the whole process of signing up to do it. And what about boards that deny you even visual access - unless you sign up. That simply drives me mad - that to even inspect the place, to see if it suits you needs, you have to go through the whole signing up process to do it.
