if you truly are concerned about revealing your location, consider this:
this website tracks your IP address. it doesn't take much effort to find your exact location just from your use of this forum or any other website you go to, for that matter.
using a proxy would help mask your location, but the time and trouble it takes to add a proxy server wouldn't make it worth it, not to mention if your ISP would even allow you to use a proxy server.
contrary to popular belief, being on the internet does not make you anonymous.
