@Daniel good question. I'd been assuming that the example questions need to be re-asked, especially since the A51 size limit is so low and often they need to be fleshed out more, but I don't know. I also assume that people who asked the sample questions get first crack at asking those questions for real (as a courtesy convention, I mean). I hope we find out soon!
@Daniel @MonicaCellio I'm pretty sure there's no relationship between example questions on the proposal and actual questions on the site. They're in two different formats and for two different purposes.
@MonicaCellio ... I doubt much courtesy is necessary to reserve questions. It takes effort to post a question properly, so they tend to get posted by the people most interested
@rosenjcb See Hapardes: hebrewbooks.org/12206 there are probably more than a hundred of them. There are some serious articles there, some light ones (Torah current events). Also see Hamaor: hebrewbooks.org/27798
@rosenjcb also see hebrewbooks.org/journals . There are many hard/Yiddish ones, but once you find a good journal, you could probably spend days on it.
