where can I find this requirements?

yes, that's the idea, because there isn't a correct answer for discursive answers, for some there's a model answer but that doesn't mean it is the only one, so people could study for their test based on previous tests and other users answers

questions would be only posted by moderators/admins, it makes sense to the site theme (not in my opinion but this is what client wants). site is about questions that appeared in interview tests for government jobs, so it has a limited set of questions

I s there a privileges for controlling what a user can or can't do based on karma (or any other arbitrary condition I would like)?

I intend to make a site where only the moderators could ask a question for example and would like to give more power to users with more karma and maybe I could even differentiate a little paid users from free users (like paid users don't get ads)

thanks
