Don't feel like trying to find the thread, but this has been asked many times already. Zam.com does not have plans to open a Vanguard site, and the reasons were sound. There should be a thread with a really good explanation as to why, somewhere on the first couple pages here in the feedback forum.
Admins, can we get a temp stickey with Allakhazam's reasons for not hosting a Vanguard site? These threads pop up every few days, I think that warrants a temp sticky.
