GrUSP is organising a tweet contest and its prizes will be two tickets, one for each conference. The contest will start today (March 29th) at 1pm CEST and will end April 1st at 7pm CEST.
Anyone can enter - all you have to do is tweet a post with a few things: the "#grsup" hashtag, a mention of the twitter accounts for the events, a link to the conference site and something about the event. Be sure and get those tweets posted before April 1st a 9am CEST - they'll pick the winners soon after! (Oh and multiple entries are accepted so the more you tweet, the better your chances!)
