Proud new Android owner!

Hi all, I come from a long line of crappy messaging phones and my most recent nokia e71x (my first and only smartphone until now). I am now the proud owner of an ATT Samsung Captivate. I love the phone, love android, and love tinkering with it. I am a soon to be graduate in the IT field and felt it was time to step up to the big leagues in terms of a smart phone. I also work part time at "The Shack" until I start my internship, so I get a good taste of the smartphone world at work. I am rooted and running cognition 3.04. I personally rooted it but a school friend flashed the custom rom. I am super eager to learn more and happy to a part of the android family.

P.S. Any advice for my phone specifically would be awesome.
