[Plugin: WP buddypress] How to rename “wire” etc…

Hello everbody!

I am currently setting up an online community for the first time. I am a frequent worpress user, yet this one problem occurs:

I don’t like the section name “wire”. I’d much rather use something like “guestbook” or “short note” for it, but I cannot find the place to change it in the backend. It is not in the theme’s CSS editor. If it was up to me, I’d remove the whole wire function. It doesnt make much sense for my purposes.

Same goes for the titles “Blog” of the Blog page or “Group/member listings” on the group/member pages- I can’t find the spot where I can change these titles 🙁

Right now I am using WordPress MU 2.9.1.1 Buddy Press latest version The free “Cosmic Buddy” Theme I do have the “Enable Theme and Plugin Editor” and I could change the navbar button names with it and many other things, but not buddypress specific functions titles.
