At my son's school, the student union has put up posters with the heading "engage yourself as a student!". My son thinks this sounds like "Swenglish", and I can't help agreeing with him, but since neither of us are native speakers of English, we're not entirely sure. The dictionaries that we've consulted don't really give a conclusive answer, so, now I'm asking you instead:
Is "engage yourself as a student" (intended in the sense 'get involved as a student') idiomatic in English?
It's primarily the use of the reflexive pronoun we find a bit unidiomatic.
