Question about starting a collab project

Hi all! I’m thinking in starting a collaboration project for a small free-to-play game that I’ve been making for the last 3 months but I’ve reach the point where I’m not very sure how to proceed since I’m new at starting game projects of my own (I’ve made two very small games and did an internship programming a commercial IOS game but I didn’t start any of those projects)

I am following this guide: http://forum.unity3d.com/threads/136192-Collaboration-Joining-a-project-running-your-own-and-why-projects-fail

I have successfully completed the Game Concept Document and I’m currently writing the Game Design Document, but I have a doubt with the widely recommended NDA. If I don’t have a company can I still make one of them? if so, how would it be? I want to make one since I’ve read that it makes more likely that my project is taken seriously (And since it seems that the collab section is mostly ignored, I have to make sure my project seriously stand out).

Thanks in advance for your time!

My 2 cents is to use indieDB instead of the collab forum…

Thanks for the tip! will check it out

Ok, I’ve been checking the proposed webpages (also http://www.develteam.com/, thanks to @SpacePixel) but now I have another doubt:

If I have a game concept and game design (and a 50% playable demo made by myself). Should I look for a game producer or a game developer to pitch the idea and start the team recruiting with the possibility of the NDA?

Any help from someone who has gone through this will be greatly appreciated. Thanks in advance for your time!
