CMS system and site navigation questions I think

[GamingVidz.com]

I recently came upon this site by accident actually, and have been looking for a good CMS myself. So is this something that is really similar to PHP - Nuke? Also, this forum doesn't seem to feature as much support as vbulletin.com. I.E. no pre-sales question forum etc, unless i"m just missing it. I can't even find out how much this thing costs. Any help heh, I'm a noob, but a noob with money.

1: Brian & his crew here give support far better than any I have seen. Period.
2: PHPNuke? Kinda. I believe it is far superior and much easier.
3: CMPS is free of charge. Hence no "Pre-Sales" support. But you are required to have a current, valid vBulletin license.
