Try different searches using your provider name, your email address, your phone number, city, (including former names or phone numbers you may have used) etc. If you have reviews here on TER, then your profile should show up in one of those searches. If you don't have any reviews yet, then you have to wait for your first review. The first reviewer will set the profile.
Once you find your reviews, (or receive your first one) then email admin at
[email protected], and ask them to link your review profile to your username. Once that is done, a link to your reviews will be under your username everytime you post on the discussion boards. Also you will get Free Limited Provider VIP, which will allow you to read your own reviews and to receive and send PMs.
You are also allowed to make changes on your profile. As said earlier, the reviewer sets the profile, so there may be some incorrect info ir a lot of "don't knows." You can fix that through problem reports or by contacting admin.
Good Luck.
One more thing: It is a lot easier to link your profile to your username if you used the same email address that is on your profile, to sign up for your user account.
