" I'm with you"

Someone else, you're preaching to the choir.

"Someone else, you're preaching to the choir. "

:-)

Just wanted to add that usually when a person says "You're preaching to the choir" the implication is, "Don't waste your time convincing me, I'm already on your side."

aha, so its usa is a lil bit different than the others, hmm ic.
BTW someone, is it "use" or "usage" here?

I'd say usage.

Eastie,
I was wondering how to use the word "Kudos" when in agreement with someone.
