Im surprised that this hasnt already been suggested, but then I suck at using teh search button so it may well have been
Concise description:
Suggestion - "beginner" game for new users
Specifics:
1. website signs new recruit up to a "beginner" game upon registration
2. only new recruits signed up for "beginner" games
3. use a default game for "beginner" game - 3 player, classic, seq, flat?
4. allow new recruits to progress to public games after successful completion of "beginner" game
This will improve the following aspects of the site:
1. reduce the impact of new recruits deadbeating
2. allow new players to find their feet in game play against other new recruits
Limited amount of options may be a good idea - small choice of maps, casual or speed game
