ChurchCrunch.com is an awesome blog--essential really.  In today's post, @Human3rror gives you the Officially-Unofficial guide to getting the most out of your Catalyst experience.

Here are a few of his tips:

- Mobile device (can you say iPhone?) is essential. Please don’t embarrass yourself by not having one.

- Don’t forget your clothes and some extra underwear cause you may drop a bomb (and I don’t mean figuratively) during the keynotes.

- Prep your Twitter-streams...the official hashtag is #CAT09.

- Turn down your device’s brightness setting. That stuff blinds foo! And it’s obnoxious. It’ll also make your device last longer, so there’s utility here folks.

- Bring some meds cause you’re going to get head-knocked by awesomeness.
