Challenges are very powerful and unlimited (if I may say so myself).

 

There is no limit to the amount you can have running at the same time of any type.

 

The only real limitation is that any one game can only be active for one challenge at a time.

 

In the Challenge ACP, you can remove individual players from challenges.

 

In the ACP, you can edit any challenge too... can even change the type of challenge or the Date to end it, plus # of tries/players, rewards, entry fees, etc.

In the future, Clubs may be incorporated for Team Challenges.  (Only thing with clubs is that someone can belong to multiple clubs, unless monitored.)

 

Also, coming sooner or later will be the ability for Admin's or Mod's to place or approve people entering a challenge and possible Team assignment.  It really boils down to the interfaces for this stuff, trying to keep everything as lean as possible.

 

Suggestions are more than welcome too.
