Maybe chemistry(dot)com or okcupid?

A good friend of mine was in a long-term relationship that fell apart a few years ago. She took some time to regroup and has been trying her luck on Match for the past 6 months or so. She's becoming really frustrated.

She defaulted to Match because ... well, because she'd heard about it.

Are there particular on-line dating sites that lesbians in this area tend to use over others? She's just turned 50 and is not looking for hook-ups - she wants to find a partner, in case that matters.

Thank you!
