It's not just these boards. TLA's are everywhere these days, and if not TLA's then XTLAs rule. There are few things more frustrating than being at a business meeting where people use this practise. It has to be realised that not everybody comes from the same background and not everybody understands what the TLA's mean.
Just in case - TLA = Three Letter Acronym
XTLA = Extended Three Letter Acronym i.e. acronym of 4 letters or greater
