K, as you know, I love nearly all things Google.
Well, Google has a "Calendar" facility, with a built-in ability to allow anyone in the world to view the Calendar. It may even have collaboration, allowing more than 1 person to edit the entries. This obviously wouldn't be seamless with the iowadg site, but it might save somebody some work if there isn't a readily available and easy-to-use calendaring function.
Also, Google has their shared spreadsheets (for viewing and/or editing) function, which may or may not come in handy for any number of distributed organizational tasks.
Ask if questions.
