Not really a forum guy, but I figured I'd share this to you guys.
I haven't seen much out there besides tankspot, but I did give this site a look from a link that my friend gave me recently. This site has some really well done videos and a few other relatively rare features. They seem like they are just getting it all up and stuff so I expect things to only get a lot better. From what it sounds a lot of the people involved in running the site are actually from the guild <vodka> which got some US firsts recently. Worth checking it out for sure.

The Cho'gall video is what I went there to look at and it was really helpful.
