Ok, well try searching the first page of "Interviews, Jobs & soponsorship", about a dozen posts below this post, entitled "BMI REGIONAL".
Sure there are no easy answers and no single post will tell the whole story but if you read the entire thread carefully it will anwer many questions... enjoy and good luck.

Also worth searching Pprune via Google for 'bmi' since pprune search engine will not do that. You have to type the following in to Google:
"bmi site:www.pprune.org"
