Math rendering default changed to always PNG
 

Further to Ynot's post about math rendering. I have changed the default to always render math using PNG images. I thought that I'd already done this but it must have disappeared as I upgraded the Mediawiki software before the launch. Anyway, PNG is now the default for new users and users who are not logged in.

I also ran a database query to change the math rendering preference for all current users from the previous default (PNG+MathML) to render only with PNG. If you prefer the PNG+MathML mix you can always change it back in your preferences.
