This is the near duplicate of a post I put on Meta FL&U and Lauren suggested I posted here too.
In 2012 the guest of honour of Expolangues, an exhibition dedicated to the teaching and learning of languages held in Paris every winter (1–4 February in 2012), is the French language. I suggested we could promote FL&UFL&U on that occasion. Since this yearly exhibition is essentially visited by teachers and learners from "all" languages would it sound like a good idea to promote EL&U (and other Stack Exchange Language sites) as well?
I'm thinking of posters or leaflets that I would have on the stall I help organize. Unfortunately we won't have an Internet access on the stall, so we'd have to stick to paper.
