i find two things bad about this idea which if they changed i would be more willing to use it.
1. the "forum" part, which i don't get. there is no reason for it to be like a forum in my opinion. it needs to be like a job "board" instead it can have two sections one where people post jobs and the other where people post their skills and what they are willing to do.
2. the "free part". the website needs to look serious from day one for people to go there. nobody is going to bother creating an account on a website that is using free hosting and domain which can go away tomorrow! not to mention that these things don't get high ranks in search engines!
