Before I start, let me say that I am a big fan of MFAs.
Can you imagine a world without acronyms? Some of them are really useful; imagine how many time you have to spent on typing if you cannot just write FYI, IMHO, FSFE, or most important RTFM. But they are not only useful, they also are very kool -- e.g. KDE, K3b, GNU... (yes, look them up yourself ;-P ).
But sometimes they can be very confusing, too. And I am really glad I can use dict to look them up. For example with mails:
Today I heard about MFAs, but dict gives me:
"No definitions found for 'MFA'".
Mechtilde, Frosch, Yalla, Byte, DocKane, Mikeadvo, Rainer_work, Mario and Kerstin: You are the heros of the day!!! Thank you very much for your work!!!
