My own experience is with LinguistList’s EasyAbs, but I just learned that there’s a competitor out there. EasyChair, like EasyAbs, is “designed to help conference organisers to cope with the complexity of the refereeing process”. Read more about it at easychair.org. This is a rare instance in which I am posting a product that I have not tried, myself, because I want others’ opinions on it!
Everything you ever wanted to know about designing a poster for an academic conference: In a straightforward and somewhat humorous piece, Colin Purrington shares all: what to expect at a conference, what to do and what not to do for your poster, links to poster templates (his own and others), and all sorts of other useful conference-related advice (e.g. have b&w 8.5 x 11 inch printouts of your poster available for people to take home, and tack these up “take one!” style below your poster). It’s a fantastic starting point for first-timers, in particular. Honestly, there are so many BAD POSTERS at these things, that it’s easy–but very much worth it– to learn to stand out!
