Three letters: M L S.
I'm a soccer fan and supporters groups have been a major reason for MLS' growth. Seattle has a fan marching band. Philadelphia had a thousands-strong supporters' group before it had a team.
What I would like to see is for the team to clear out a section or two for standing and chanting. Populate it with people who wish to enjoy the game this way. Having a few sections leading the way will hopefully improve the atmosphere throughout.
TheKey, if you really want to do something about it (and this is a good start), find like minded individuals and go to the team as a season ticket holders and find ways to make it happen.
