Let users change certain AppCfg values via the Admin interface -- especially ones that will change more often.
On the dashboard, include a table with the full configuration (minus sensitive data). Allow some values to be changed:
- OpenRegistration (checkbox)
- MinUsernameLen (number)
- MaxBlogs (number)
- PublicStats (checkbox)
- Private (checkbox)
Each should also have some information below it about what the setting does.
