Here is the Statement of User Requirements
My idea is to create a gaming league where players can register and create a profile.

That player can then create a team along with a team profile page.

From the team area the Administrator of that team (Team Creator) can then invite players to play for that team.

The maximum amount of players to a team is 10 players.

When the teams are created matches between two teams can then be organised.
Matches are played on their Xbox consoles and scores are reported back to the website.

The scores will then give out points to the teams which will place them in a league table.

From these Requirements we can identify the 'Things of Interest' as :-
1. Games
2. Leagues
3. Matches
4. Players
5. Teams
