How do I change the Logging in & out URLs?

I would really like to be able to have it go elsewhere than where it currently goes when you log in & out of a Joomla site using Community Builder. I was wondering if anyone would be able to tell me how or atleast tell me which file I would need to edit to be able to do it.

Thanks a lot either way.

Alright, I figured out how to change the place where it goes when you log in, but I still haven't figured out how to make it change where it goes when I log out. I'm sure I'll eventually figure it out, but if any of you have any help for me, it would be much appreciated. Thanks either way...
