I’m always surprised when I check the “Selling” or “Wanted” sections on this website. In general, every response to an ad or request asks, “where are you located”. Since members are able to respond, I’ll assume they are signed in. 

Just tap or click on the poster’s name, and all the info comes up. Name, address, phone number, email address. No need to ask........ try it now. Click on my name (under the photo to the left). It works.
