When searching for tournaments, allow location as a filter so users can discover tournaments to join. This would be an amazing feature because more users because it will increase visibility and enrollment in tournaments.

For example, askFRED.net is the de-facto fencing tournament organization website in the entire United States. All enrollment information and events are managed/organized through the website (although they have no bracket software, third party software interfaces with their website). Any fencer, or parent of fencer, can search for tournaments by region, state, city, date, even on a map and sign up.

I don't think this would be a tremendously difficult feature to add, since you really just need to add a location to tournaments. It can be basic for now, and perhaps load a map with locations eventually as the home page or something cool!
