TechIMOids - sounds too much like hemorrhoid. I'm sure most members sit on a comfortable surfing surface. Personally, I use a thick pillow.
TechIMOans - Tech-I-MOans - sounds like a computer problem turns competent members into inept whiners and moaners.
TechIMOlians - sounds like a RICH PC or Mac owner. Those types have someone else fix their problems.
I like Geeks.
