Which is the best CMS to use with Bluehost?

[shauna]

I just purchased my domain and hosting. Bluehost directs me to Simplescripts but there are so many options here, I don't know where to start. I'd like my site to be linked with existing facebook & twitter pages as well as the you tube channel. It will be used for member login, forum, surveys, updates, events calendar, and content linked from the previously mentioned pages. Hopefully something will have the capability to sort members into groups using options they chose when signing up. Does anyone know which site builder is best for what I want?
