There used to be a British Diabetic Association but that's now Diabetes UK. They made a sensible move, I think. Take a look at the web addresses of the other links that I gave...
bda.org, bda.uk.com, bda.org.uk (OK the Dyslexia one is bdadyslexia.org.uk)
This is why I hate acronyms. I get confused by acronyms. I feel excluded when people speak using them. Why make an acronym? (Yes, MOODLE is an acronym (so is LASER). They have morphed into words.) My argument is to beware of using acronyms lest they confuse. Nuff said.
