In order to limit the number of "non research level" questions asked on cstheory (that cause annoying downvotes/see-the-FAQ comments/migration/closing), I think that a good idea would be to add a short but visible subtitle under the "Theoretical Computer Science" to underline the scope of the site, something like:
"CSTheory site is for research level questions in theoretical computer science, see FAQ for more details. If you have a non research level question (undergraduate/graduate student level) please consider to ask it on Computer Science cs.stackexchange.com first".
And/Or it could be added just before the "title" field in the "Ask question" form. Now there is a box on the right, but it doesn't mention the "research level requirement" and in that position it looks more like an advertisement box (i.e. nobody will ever read it :).
