That is the site...it's just the event called Comic-Con on this site is known as CCI - Comic-Con International. There is a link on the page to CCI or you can just add /cci to the URL given. CC is much bigger than just Cosplay, it's for everybody who's into film, video games, comics or anime.
Also, to the admins...July 19th-23rd are the dates (they aren't on the forum landing page), 19th being the preview night for press/industry (like the early access at E3).
Comic-Con always rules because there's so much to do there, and there lots of celebs. The Star Wars cast (original trilogy) is going to there this year, well, some of them. I also hope they show off the Eragon trailer to the public...ever since I saw it at E3 I've been wanting more.
The only true wisdom consists in knowing that you know nothing.
