Of course, we don't expect you +to already start working seriously on your project, but any input you're giving +us will make it easier for us to justify selectiong your specific proposal. At +this time, it is not quantity that matters, and it also is not *the perfect +patch* we're waiting for, but it is rather that we see how you're generally +able to work with the code. + +If you have any questions, don't be shy: please ask! Nobody expects you to +know everything.
