IMHO also means "In My Humble Opinion"
Of course there are many variations for a majority of these acronyms. You just need to keep in mind which ones mean what according to the forum you are on.
In effort to KISS (Keep is Short and Simple, Keep is Short and Sweet, or Keep it Short Stupid!) I think the general idea has been reached.
We could continue to add until IMHO the thread becomes FUBAR or FUTATABAR, BOC YMMV!
