The American Geophysical Union just tweeted out a link to a virtual poster competition for undergraduates. You have to sign up my 3 March 2016 for the spring round. Anyone who wants their poster critiqued beforehand... my email address is not hard to find.
Additional: When I retweeted the link, Terry McGlynn responded:
AGU meets in San Fran, too $$ for students. The fix? Just put them on the internet. They need a real network too!
This is a valid point. Is a “virtual poster session” the academic equivalent of the “kiddie pool”: intended to be a safe environment, but kind of demeaning at some point?
