Of course if they post on a discussion board, you can click the link under their handle (but I know you know that already Mac.) Other than that I don't think you can search by "handle." It actually wouldn't be a bad idea to add the handle to the profile too. Maybe you should suggest that on the S&P board.

There is a TER ID and a providers
name, but what is the handle?

Take for example some one on this
board Fallon Kelly, in the thread below
this one, and search google with the "site"
command:

site:www.theeroticreview.com "fallon kelly"  

You will get 258 results, if you don't want
the discussion board posts in your results
put this in the command:

site:www.theeroticreview.com "fallon kelly" -discussion  
and you only get 134 results

Lets do it with a common name like Nikki:

site:www.theeroticreview.com nikki                        
We get 172,00 results

put in a city: salt lake

site:www.theeroticreview.com nikki salt lake
And we get 362 results

You can even use that line command
to search the details of a review, but
not the juicy details.

I don't know if this is what you meant?

then you can go to search reveiws, put in that name and research that way.

If it is a unique name, then no problem.  However, it it is a common name like Brandy, then you'll get hundreds of hits.

If you know anything else about her like her city or physical characteristics, you can use those filters to further winow down the list.
