separating in twos?

why are my members split into twos - there's a separating line every two members (apart from the first member).

I'd like this separating line to be between every member - how do I do that?

(can't show you a direct link as this is a member only site....thanks)

Guessing it has something to do with your joomla template - inspect css using firebug to check.

much as I hate to fire up firefox, I have to admit that your advice and firebug hlped me fix the problem.

thanks!!
