I searched ["im" is a verb] in Google and didn't get anything substantial in terms of results, but I think it is time we all face it that "i.m." has become a verb. It is actually a very commonly used word in techno-babble.
Also, and I am not a lawyer so I don't know how this works but, I would also like to declare my intention to patent an eyetracking device that will sense when I look at an IM window and auto-magically make the window stop blinking. I just have to actually invent it first.
