The deadline has been extended for the Narrative and Interactive Learning Environment (NILE) conference 2008. The deadline is now Mon 10th March. See www.JudyRobertson.typepad.com/NILE_2008 if you're thinking of whipping something together at the last moment.
It's always a fun conference (or at least it was before I drew the short draw to organise it ;-) ). It's small, and friendly and we make an effort to have stuff to do as well as stuff to listen to.
