The Geek'tionary

A dictionary.

A dictionary containing alot of uncommon, if not strange abbreviation, mostly are from the IT and tele industry. I have actually had this digital gem hidden away for years. Just stumbled upon it by change the other day and figured it was time to put it to some use - I cannot even recall how I came by it in the first place.
