I don't know how it is for screenshots, but when I submitted game info to them it was such a faff that I've not bothered since. Maybe screenshots is different, but I wouldn't want to take a whole load of nice shots only to have a random mod turn them all down for no given reason.
Also bear in mind that this is the same Gamefaqs that considers any language other than English to be unworthy of attention and thus auto-censors posts so that it's impossible to talk about certain characters, phrases or ideas without being blocked.
It'd be nice to have a more user-friendly experience, you know? Unfortunately, GameFAQs is pretty popular, and most rivaling/copycat sites fail to catch the users' attention. The way I see it, the site in question must be open to editing with an undo feature, and limited moderation -- like a wiki site. It'd feature user-made strategy guides that anyone can add content to. The formatting could rival that of any strategy guide in print.
Alright, enough dreaming. I need to get back to work.
