Yes, it would be great if everyone would give there city, state, country location on discussions, for sale and want ad posts. This would be a huge help when trying to respond to questions or for items wanted. Sometimes if I don't see a location I feel it makes little or no sense responding.
Another thought....I see many WANT ads that have "anywhere" stated in the area asking for their city and state. This is not supposed to be used for where you would like the wanted item to come from, but rather the address/location of the person placing the ad. The location of a person placing a want ad may be a big factor in getting someone who has that part to respond.
