Apologies if anyone has already mentioned this, but I only heard about it today:
For the last four years, thousands of gamers have joined together annually to play for 24 hours for Extra Life – a gaming marathon in support of Children's Miracle Network Hospitals®. Gamers rally friends and family members to sponsor their play. The funds they raise go to help save and improve the lives of kids at the CMN Hospital in their community.
This is obviously a great cause and as gamers it's an opportunity to raise money whilst doing something that we love. I'm seriously thinking about doing it and thought it would be awesome to do it as a guild team if other people were interested.

Great idea! I'd definitely be up for this. It would be terrific to have a whole server doing this.
