was part of my original suggestion about import/export teams, would be handy for team sharing, RMTs and the like.
Another thing it's good for is giving your teams a once over after you're done building to make sure you didn't miss anything.
The export to text option need make a team that can be used in the box "import to text". With this compatibility we can share teams easily, test teams of friends, of rate my team forums, etc
An extension of this would be allowing users to import and export whole boxes for even easier team construction, but that's a lower priority.
