Are you talking about the ones that turned into 24/7? If so, I didn't leave, I still check there everyday. May not post as much anymore but that's because I've been playing Titanfall and I didn't really get into Ghosts.
Ahh, did the link change or something? I never really leave forums unless the link changes or the site itself goes down. Because I have a lot of sites bookmarked that I like to check everyday and if I don't have a working link..
I probably took it out of my bookmarks when I noticed a completely different looking site. I don't really remember as it was a while ago. Is the interrogation over yet?
