Me too!
I logged in to ask the same question, and I saw your post. I received an RFE about 2/14 (proof of eligibility for employment since I submitted my I485 in Dec. 2002, I submitted my H1b approval notices from then until now) and on 2/22 I received e-mail that they received my response. Just out of curiousity, I logged in to check to the case status update page today, and my LUD was today (2/25), but the message was the same as 2/22 (we've received your response).
I think and hope this means we're close. Let's be sure to update this thread with any approvals in the near future.
