Inspired by the "Fight Club" post by Piepai, Zylopfa decided to make a web application facilitating duel matchup, gold or honor duels, between 2 players.

One player has to make the request at this site, and the other player whom he challenged for duel will receive email / sms or other with the duel info.

There is a link in this email to decline, accept and accept with changes of time and/or place.

Once both duelists have agreed to time and place the judge (also choosen at the time of creating the challenge), is informed
via email, which contains a secret link to a page where he can
update the match with who won or lost.

Also the duellists will receive a final email that their duel is ready .

Once the match has taken place, and the judge have made feedback on the site (from using the link in the email), the match is updated with the winner and an internal scoring system is updated.

I have attached a incomplete diagram of the application.
please come with suggestions in this tread.

The application is already being made but can be altered with good ideas!
