3bysmom - I think I may have found a way. First, log-in to your CougarTrail account. On the left side under Personal Info, look for E-mail Addresses and Personal Web Page. Depending on how many e-mail addresses you supplied in the application, your new CofC address should be listed under number 3, 4, or maybe 5. Look for the address that follows his format:
xxxxxxxxx@edisto.cofc.edu. I just checked mine today, and it said "active".
I'm not 100% sure that this is the right way to check, but I've not seen anything better yet.
Good luck!
