In case you did not hear via twitter (@ourarena or #ArenaChMS) or the Arena blog, Chris Rivers will be giving a 10,000 foot demonstration of Arena ChMS. If you have never seen Arena in action and are considering a switch from your current Church Management System (ChMS) I would definitely encourage you to sign up for the Sept 16th demo next week.
The demo won't even scratch the surface of all the features and possibilities Arena has, but it's definitely a good starting point.
