It is absolutely awesome! You make your own virtual person (kind of like in the computer game "The Sims") and then you can chat with other people. You can sit on a moving ferris wheel with them, in a Starbucks, on a rooftop, or even in a dungeon! With your account, which is free, you get 1000 free credits to buy new clothes, scenes, etc. From then on, it costs $1 for 1000 credits. But the money issue is not a problem at all--it's just for "cooler" things. The actual chat and clothes they give you to start out are awesome--and those are free!
After downloading, I made 50x1 get it as well and we had a blast! We hugged and beat each other up and just chatted like normal.
So, since the other people on there are sort of weird (this one girl kept making out with 50x1 o.o), I thought I'd let LF people know about this if they wanna chat.

Warning: The program does some freaky stuff when you first download it. Windows tried to block it for both 50x1 and I, but with most computers that can be solved simply by clicking "Grant Access" when the prompt comes up. With other computers though, as with my boyfriend, Werwek on this site, it just won't complete the download. I'll let you guys know what happens when we figure out how to fix that problem.
