Reminder: Extra Life charity marathon taking place today

We've all had gaming sessions so lengthy that a thin layer of film formed between our posteriors and our furniture -- but rarely have we ever had a worthwhile reason for doing so. However, as of 9 a.m. today, gaggles of stick-to-it-ive gamers set off on a 24-hour gaming marathon to raise money for the Texas Children's Cancer Center, as part of Sarcastic Gamer's Extra Life charity event.

While it's too late to join in today's festivities, a "Rain Date", scheduled for next Saturday, will allow latecomers to garner donations and participate in the marathon. Not interested in developing bedsores? You could always donate directly to the cause -- or offer participants in your area a tall cup of coffee (or a much appreciated hand massage).
