link removed is a good one, but to actually contact someone on there, either you or your match has to have a star membership which cost a little money. Do pay attention to the picture or their description tho, because a lot of times people would hide their contact info in there.
what i usually do is to search people using yahoo! profiles:
link removed?.oc=a
where it says "enter a location" you can put in your city, so you'll find people that's in your area. you can also check the "view only profiles with pictures" so you can see what they look like. and "view only online profiles" which you can start talking to them right away. of course that requires you to have yahoo! messenger, which is free to download and is one of the best messenger services out there.
hope that helps ^_^ PM me if you like
