I think TER should have a separate category for doubles...It would sure makes it easier to search in the rankings. Any thoughts?

for "REALLY BI".  Most of your doubles will come up that way.

Post any double reviews on the ladys regular profile.

First, you are right and many people agree with you. I wasn't around TER in the beginning, but I don't think that TER has evolved as quickly as, say, Darwin's finches.  

A passable fix is to search "AND" in the name field. Most doubles are linked by "AND" or "&" (and another odd conjunction or two). You will get some extra hits (cANDy, amANDa, and so on) but you will also get a healthy dose of "alice AND betsy" type listings. Searching "&" also gets hits but I think that there are more "AND"s than "&"s.  

Yes, TER should upgrade numerous features, including a separate Profile design for multiples but don't hold your breath waiting for it to happen
