Not for me.... everything has stayed the same except for my CL. I tried asking those questions but the person I spoke with didn't speak English very well so I am going to try to call back and get someone else later tonight.
I called AMEX up a couple hours ago. I got my card last month with a 1k limit. Called them up and asked for another 1500. Got it in literally about 1 second. That might have been the easiest thing I ever did. Very glad I called them...
