I know there's more... but I can't think of them right now (I have them all saved as favorites on my home computer.
I don't really like videofitness.com all that much. It's a lot different than this is, and I don't feel as comfortable posting there. I like it for the reviews and some other features, but not for the general forum. I hang out on the WW site, but that could barely be called a "fitness" site. I'm not on the message boards at WW as much anymore. Too much whining for my taste - not to be cruel or anything, but I find the more I surround myself with negativity, the more it seeps into my pores or something. I prefer to surround myself with positive things and uplifting people! That's why I love this site!! I find all I need right here. Great question, by the way!!
