Bah, Aristotle, apply now. You sound like you're afraid to submit your ideas. Just accept that they aren't the best ideas and send them in anyway. If you accept that, then you are leaving room for improvement and you have nothing to be afraid of. I'd be scared if I tried to send in a perfect idea. The problem isn't getting ideas, the problem is the courage to submit them for fear of being rejected.
I submitted some odd 5 ideas. I've worked for Goodman Games before so I sort of just tossed them out there. When I have more time I'll probably coble together something more serrious. Most of the ideas I haven't started. They're not expected you to have the products done. They're idea fishing.
Serriously, submit some ideas. Remember that they are also looking for people to just help write other stuff. Submitting puts you on their radar and you could end getting asked to work on stuff. Posting that you aren't going to submit is safer, but they probably won't ask you to work for them that way.
The worst thing they are going to do is send you a very polite letter turning down your ideas. Wizards sends the best rejection letters but Goodman is pretty good too. They might not be sending them out though with such large numbers of submissions though.
The worst thing you are going to have to endure is some stuck up writer telling you what to do on the forums!! Submit or I'll make a silly face at you and say Ni!
You stuck your foot out. Now you're going to get dragged into the door. Welcome to the Twilight, er, Goodman Games' Zone! Write back when you've made a submission!
