What privacy?

Okay, so.. I've just started to get my feet wet with this whole blogging thing. Although I have an established family blog (by invite only), this whole "trying to be annonymous" thing is HORRIBLE! I keep finding little pieces of the "real" me that I have left for the whole world to see. I am unsure how to link both of my blogs to one email address for my own easy access, and keep them seperate at the same time. Any suggestions?
