Calling all paleo/crossfit people! New and old.

Just re-joined MFP. I started doing a paleo based diet and a crossfit based workout routine. Looking for some friends who either are new and learning about these or old pros who have a lot of advice to give along the way. I eat as much of a paleo diet as I can afford. I also just started working out with weights. I was always the type who thought girls shouldn't lift heavy because they would get bulky. WRONG! Any tips or tricks anyone wants to share would be great!
