Think through what kind of project you are submitting. If you don’t think you can pull together the idea, be able to implement this with the community, or be able to share (whether it succeeds or not) how the progress of the idea is coming along, than please wait a few months. We don’t like telling some groups yes and then having them drop out at the last minute. It’s a fairness thing. The idea doesn’t need to be super polished ether. We just want to make sure that you are available to present after submitting.
