Hi Tristan,
I took the survey, but the thing is, I doubt many people would want to pay to be a part of a website like the one you are speaking of. There are already at least 6 (by my count) indie video game employment websites where you can ask for help or offer your own, for free.
Now, I'm not saying don't create a website--I strongly suggest you make another of these types of websites, they're very helpful and have helped me make money!
But, if you're asking for a fee, it would probably turn many people off to the idea.
Is there anything your website is offering that you don't think any other website is? I'm just curious, because if there was something that was incredibly unique about your website that really made things happen, I might be interested in signing up, even for a fee.
