Relax, you are getting bent out of shape over a few yahoos. At least stick your complaint in a thread where it makes sense. I just spent 5 minutes trying to figure out who wound you up.
Most of us answer whatever questions we can, some people answer questions they can't, I sometimes do not even know if I am giving advice on a ped or a scooter but it does not bother me at all. What I will not do is answer a question if I do not at least think I know the answer, nor will I call a scooter a moped.
