F1000Posters (http://f1000.com/posters) is an open access repository that hosts posters and oral presentation slides in biology and medicine, and can also be considered a pre-print server. It allows researchers to extend the visibility of their work outside of the conference hall, maximising the return on the time, effort and money invested in creating each presentation. Many of the posters are submitted with their subsequent research article added to them when it is eventually published. It also completely free to submit.
