AnceStories has announced the upcoming ScanFest. This will be the first one I participate in. If I do my time zone math correctly, it will be from 1 pm to 4 pm Central Daylight Time.
I have reread Sally Jacobs' "8 Blunders People Make" and cleared some albums of photographs I wish to scan. There are probably more than I can scan in 3 hours, but whatever I accomplish will be more than I would have probably done anyway.
I don't believe it's too late to sign up now, and you don't have to be a blogger to do so - Miriam includes instructions in her post.
