You can change your Location, Country, Postal Code and Time Zone.
Presumably, however, when searching for LOCAL tournaments, chess.com uses the location of your ISP - which you cannot specify explicitly.
You don't seem to show up on the interactive map.
im surprised that i cant figure this out....but how do i change my "home location"? for example, if i am searching in the "local" tab for tournaments or clubs or whatever, it has a set home location and i cant figure out how to change that anywhere...
