www.team639.org does same thing. We wrote it all in php/mySQL... all info/dates/pics/calendar are databased such so that all information can be edited online (no html crap)... Makes things very simple. We also have user levels regarding what members, team captains, teachers, parents, etc can do such as being allowed to mass mail everyone. The design took a loooong time as it's completely original but well worth it.
