All I know is what's on the site, next pumps on Tuesday and Thursday at 5 PM ET, so there's one today, on Bittrex. Two hours before the pump, the "Next Pump" page on the site will have the IRC client activated and you'll be able to join the channel through which the organizers control the pump. They pick 8-16 coins, number them, then the first hash of the newest mined Doge hash will determine which coin gets pumped. Once that's announced by the announcer bot, you quickly buy in and immediately set a sell price to an amount you think it might sell for. The way to do it is to be quick and not be greedy.
