I think you should move away from Wikimedia as a CMS platform. It's crusty, looks terrible, and is a trademarked for "half-assed projects" as far as I'm concerned. To be brutally honest right now it looks like someone shuffled through the Wikimedia plugin bin and slapped it together without any thought to aesthetic.

A simple static website with the What, Why, and How as a portal to a better, light weight, CMS would be far more attractive.
