Thanks for pointing me in the right direction, guys; I got this working!
I found a post on SuperUser (http://superuser.com/a/361749) that told how to do it in Chrome, and it worked!
All I did was create new the new profile, make another Opera shortcut, then add "--user-data-dir=" and the path to the new profile and; voila! 😃
Thanks, guys! 😃
