I'm going to implement a formal application system on the site either today or tomorrow. If you wouldn't mind waiting, it would be a good testing experience.
If you have any particular things you would like to talk about or bring up, feel free to PM me whenever.
Upstream repositories are now live! Upload the add-on like normal, then on the add-on page, there is now the column "repo". Click on it, and it's pretty straight forward from there.
