| | Help understanding how zip code and location works
I have zip codes turned on, and I'm having trouble understanding how it's currently working.
I'll try to explain this as best as I can so please bear with me.
When I register as a new user, I'm not asked for my zip code. I'm asked for location, which could be any text: zip, country, city, planet, etc.
When I place an ad, I can put my zip code in of course.
No matter how I log in, (admin, testcalifornia, testnewyork, etc.) all distances are computed from my real location in Central Illinois (61701). I can't find anywhere in the data base where my local zip is stored, or where I was asked for that information (besides posting ads.)
Where is the system getting "the viewers" zip code?
