Agreeing

Absolutely.

Exactly.

I can live with that.

I concur.

I couldn't agree with you more.

I don't have a problem with that.

I totally agree.

I'm inclined to agree.

I'm not complaining.

It's a go.

No objections here.

No problem.

Okay, if that's what you want.

Really.

Right.

Sounds good to me.

Sure!

That would seem to be correct.

That's got my stamp / seal of approval.

Yes, without a doubt.

You can say that again.

You have my whole-hearted support.

You won't get a 'no' from me.
