Can you feel it in the air? It’s almost Hacker Cup time at Facebook. The social network announced in a post on the Facebook Engineering page that registration is now open for the 2013 Facebook Hacker Cup.
Today only, we're offering $100 off AllFacebook Marketing Conference and AllTwitter Marketing Conference and $200 off a Combo Pass to attend both events. This offer expires at midnight, so register now with the code ONEDAY and save. 
Marketers who are interested in promoting and getting attendees to register for events but find the Facebook events functionality to be limited may want to consider Constant Contact.
