As mentioned by SpencerG on https://webapps.meta.stackexchange.com/a/5142/18147:
including research in a question is not required for question asking on Web Apps.
and:
closed questions can be reopened should they otherwise be of an adequate standard for Web Apps.
How shall we request the reopening of questions closed due to lack of research? Should we cast a reopen vote? Raise a flag? Message the mods in the public chatroom? Use some other way? Something else?
I'm asking as I've tried to cast a reopen vote and raise a flag, and none of it seems to work.
