What are you on about ? Without being rude to you, that is such a ridiculous and funny idea. Mods aren't picked by how much of an expert they are with windows here or at most forums, while it does help, its hardly the decisive factor when it comes to promoting people. How would such an idea even be policed, if a new version of windows comes out do mods get demoted if they don't become experts concerning it ? Do we get a weekly written test ?
My computer knowledge is pretty average, especially when it comes to the tech side of things, but I'm a mod here and at a lot of other forums. I'd like to think its cause I've got a sensible head on my shoulders, am a good poster, know the rules, and make a solid contribution. From what I've seen, people are promoted to mods if they make a good contribution to the site, whether they are "experts" or not.
