You can still find illustrationfriday.com but it is no longer the site that once hosted a weekly prompt and sometimes offered awards. The new domain is http://www.illustrationage.com . It's still a great resource for budding illustrators, though.
Because of this change, I will be placing the group into stasis as a read-only gallery of collected illustrations. No new illustrations will be added... UNLESS there is someone who would like to curate the collection by finding good illustrations in Deviant art and add them. If you'd like to be a curator, please send me a Note.
