Many people seem to be concerned about losing info including your Buddy List after the upcoming revision:
Save it in a text document like Word, notepad or any other such program!
Open you Buddy List, use your mouse to highlight the whole list. Press Ctrl-C to copy. Switch to your new "word" document. Press Ctrl-V to copy the whole thing. Then if you need to you can type them back in the "new" program. !!
Let's help Patrice and the others by doing what we can to help ourselves!
