There are two very quick ways to check your profile number.
oneOn the CIT site, go to "My Public List" under "My Account". You should see this URL:
http://cit.cohtitan.com/profile/16367That number at the end is your CIT profile number.
twoOn the forums, click on "Profile" at the top. In the "Titan Network" section, click on the CIT icon. That will take you to the same public character list. Again, you want the number at the end of the URL.
