Question Adding abbreviations?

I like the functionality on the RPF where you get the meaning of certain abbreviations when you move your cursor over it (like BTTF, RPF, etc...). I was wondering if it is possible to add abbreviations, or if I can suggest abbreviations to someone?

In a thread I came across the abbreviations COW and IGI. I knew COW stands for Club Obi Wan, but didn't had a clue for IGI. Seems to be the abbreviation for Indy Gear Italia Forum. Maybe both abbreviations can be added to the list?
