While such questions may be on topic on Mathematics Educators, remember that MathEd.SE is a very young public beta site. Generally migrating questions to beta sites is at least slightly discouraged. In the words of Anna Lear:
Migrating to beta sites isn't something we encourage because beta should be all about a site figuring out its own voice rather than getting questions from elsewhere, but an occasional migration doesn't hurt much.
and echoed by Tim Post
...and we're very much against establishing migration paths to beta sites, we need to be absolutely sure that they're going to graduate before we facilitate a conduit for content to go to them.
While eventually a migration path would perhaps be natural, I think that for the time being stemming the potential flow by requiring migrations go through the ♦-moderators (who may then also contact the newly appointed pro tem ♦-moderators of MathEd.SE about worthiness/desirability of such questions) is a better option.
