Let's be clear. The site is about making money. The site runs on outdated tech and the administrator - who hangs around the forums using the name rugby_does_mfm - clearly know zip about web admin because the site never improves or changes in any technical sense. Technical support is non-existent. The forum is extremely basic and indeed the site as a whole is pretty basic. It doesn't offer a great deal in the way of filtering or search capabilities and the 'chat' is terrible.
The members are generally low quality people. Ration of women to men is about 1:50.
Many of the guys are desperate or frankly strange, and many of the women are attention-seekers. It's a strange place and despite being on there a year we didn't really find very many people who seemed normal.
If you want to meet people, you're far better off avoiding the site and just attending a club or using a different site. We were very unimpressed.
In summary, I would not recommend Fab Swingers to a friend.
