Just a quick DP
I applied and opened an nRewards card just shy of 2 months ago (Feb 17th) it was just reported on April 10th. The HP posted immediatly and it looks like I only dropped 1 point for the new account (I'm sure my 1-2% util and my other accounts aging is offseting the drop by a bit). I was worried that it would never post because I never had a ballance in it when the statements cut. I left 12$ on it this past month and BOOM it is finally reporting. Not sure this is related but it is part of the story.
Now I finally have 3 CC and 2 Loans reporting (I did not know that a student loan counted, so I took out a share loan from NFCU and paid off 91% the next day).
Sorry for the delay. I did not SEE a drop, but I was not actively monitoring my credit in the beginning. I knew it was really bad, so I just followed some advice I saw around here and started waiting. At this point, time is my best friend.
