...enter the TER handle in the author field and expand the number of days to 300, 600, or what have you. Then hit submit or whatever it says to begin the search. You'll get the posts by that handle going back that many days.
I think (not sure) that the search is board specific so you may have to do a search on each board to get an idea of all his/her posts. If it's an alias I don't know if this will work but it's worth a try. I just tried it with your handle and got two of your posts on this board in the last 300 days.

thought I might need to add...you don't need to fill in any other search fields to do this.

As xyz said, you can search by author, but you have to do that for every board. You can also search for reviews under the username. You can also try google. In a google search, enter the username and "theeroticreview"  you should come up with posts and reviews and anything connecting the gandle to TER. Fir example google search "pwilley theeroticreview"

Also you should realize that there are thousands of VIP members who have access to PM but never post on the boards, so you may find nothing, even though someone was able to PM you.
