One of the first and best Final Fantasy fansites I stumbled across was dedicated to FFVII & FFVIII and, while not a forum, had extremely well displayed (for the time) content detailing everything from character profiles to locations and all the shops within the locations and everything like that. It was fantastic for when I was playing FFVII (the first FF I'd played). I think FF Citadel and that site were the two I used the most at that point, and it wasn't until later when I was trying out other FF's that I discovered EoFF.
