As in last year, posting this 24 hours before so people who might be interested will have a bit of a heads up. So...
It begins ...soon.
Or in a nutshell, a charity marathon where a bunch of people (mostly from the comedy group Loading Ready Run) play one of the worst/most boring games of all time while auctioning off unique (often geeky) items, singing, performing any challenges watchers give 'em and will have call-ins from people all 'round the world and so on. Good times and sleep-deprivation all around!
There's a schedule of guest call-ins and a constantly updating wiki page for the event.
New! They've added a master schedule which has times for call-ins, driver schedules, auctions and such. And speaking 'bout the drivers, here they are. :3
For what you might walk off with from the stream, have a look at the live auction items (These tend to go to several thousands per item), silent auction items (which'll just be auctioned on the webpage, off-stream, tend to be sold for cheaper) and giveaway items which usually are randomly given away for people who donate an exact amount (or multiple thereof) during a certain time period or for drawing/writing challenges (very cheap but you'll need plenty of luck and/or skill)
And yes, it's mostly a copypaste from last year's OP, so sue me.
