As for changing your location -- go back to the registration page and find your profile. Around halfway down the page is a blank for "location". That's where you put yours. City/state is fine, by the way. We ask folks to fill that in because - especially for new members of the Forum - we don't know much or anything about you and might want to visit your place when you need help, or when you list an item for sale we'd like to know where said item is so we can make an EWAG about shipping costs and hassles. Heck -- sometimes we'll find that one of us is close enough to you that an afternoon of bench racing would be a fine way to spend some time.
As for your location that I filled in for you -- hey, it could have been worse. I ofter put in a made-up location just to jerk the chain of the new people. At least I wasn't too goofy this time. I've assigned some newbies to places like Drizzly Diarrhea, Delaware or Clenched Cloaca, Connecticut. And so on.
See? Kansas isn't such a bad place after all, is it?
