I'm surprised that the Debian website was not nore clear on how to change from stabel to testing; it's an important procedure - and not exactly obscure.
I wanted to go permanently with testing because I do NOT like reinstalling with every new release, and upgrading in place sounds good in theory, but never quite works right. And the packages in stable are just too stale.
BTW, Brian - please ignore any duplicate reply you may receive from me. I can't get Gmail to "reply to all" without apparently sending an additional reply to the last poster in the thread (that's you) also. I don't know why.
Gmail sucks. If it wasn't free . . .
