Just had a quick look, and I have 2 'complaints'.
One is that is has an age range function, I did a search using 28 as the lowest age, and it showed me quite a from from 18-28 as well as those within the range i had set.
Also, the distances can be wildly optimistic, i am guessing the mileages are as the crow flies,plus a shortcut, some of the distances shown can be as much as three times what is shown.
Other than that, it is looking good.
The only other thing I would mention is 'last online', it used to be that a profile would say when that was, now it is each day, then anything more than 15 days is 'over two weeks'. Now that could be early april, it could be 2006, is this going to be a feature that stays?
