Enter as much information as you can about her on the Search Reviews page in the Review Section.  The city would be the single most important item to limit the search.

You will get a whole batch of similar names come up and by clicking on those names you'll get to the profile pages.

By the way, if you saw this gal post and there was no link by her name to her reviews, she probably doesn't have any and therefore has no profile page.  On the off chance she may have VIP membership, you can click on her envelope by her name and send a PM, but you also have to have VIP status to do so, and I see by the fact you have no envelope, you are not VIP.

I hope this helps.

Which board? If it's a TER board she usually will have a link to her TER site. If not, but has an envelope in the "Posted by ____" section, click on that and try the name given there, in the "Search Reviews" section.
