Is there any way to enter a provider's name in a search engine on TER and have any reviews for her come up. Maybe I am computer illiterate but it seems to me I can only go through all of the providers listed until I find the name I am looking for. Thanks in advance.

The link below is from the  newbie manual. You should become familiar with the manual. It's on the top of the main page on the newbie board.
Good luck

You can specify name, regions, cities, even area codes. Each provider also has a provider ID #.
