I have to say that Plenty Of Fish is really a nice dating site. It's been surprisingly easy to use. I can recommend it, at least for women, from my experience.
One man I met on there has been dating on it for two years, looking for the right girl. That's a commitment. But he seems to not be tired of it, so that is good.
I still have new men emailing my profile, even though I'm traveling right now and unavailable. I think I should log in and make a statement that I'm not around for awhile. What do you think?
