Here's two decent friend sites for you, especially the first one if you live in the UK:

http://london.citysocialising.com/
This is a really good site because it's all about people getting together and doing something fun! There's always a get together somewhere, and you get invites in your inbox on the site. It can be anything like a nice group meal somewhere, pub visit, cinema night, theatre, sports, concerts you name it. They even have a nifty event calendar. To be a full member and access these events you will have to pay a monthly fee, but hey they gotta make a living like all other sites, so personally that doesn't bother me. I never made it that far though before I moved out of London and back to Norway, silly me.

http://www.newfriends4u.com/
This is a site I've tried properly and I did get a result, though it didn't evolve as I would've wished. The site has mostly UK members (I think) but anyone around the world can sign up. You also have to pay a monthly fee here, but there are (or at least was) ways to get around the "no email addresses in messages" rule. You just had to be clever with how you wrote your email address, all backwards for example.

My story on newfriends4u is I met a girl there who I emailed for a while and then we decided to meet up for a meal and drinks. I could tell she was holding back from the moment I met her, I was hoping for a quick hug but all I got was a very limp handshake. I thought fair enough, she's probably just a bit shy. However she was very quiet throughout the evening, even seemed not interested. After meeting up she would send me all these emails about God and loads of chain letters miles long. By that point I lost interest. I guess situations like that will happen sometimes, not great but if it ain't your thing it just ain't your thing.

Yeah I guess people can be quite different without computers to hide behind.

Thanks for posting the sites, will check them out.
