Storyblender is an intriguing video-creation (and mixing) site that is invitation-only right now, but might have some potential for English Language Learners down the line when it goes public.
Right now, though, it does offer — to everyone — a free and easy tool to create a Holiday Letter. No registration is required. Just click on the preceding link and follow the clearly laid-out process. Steps including recording a video and uploading a photo, but you can just skip them and still end-up with a decent electronic holiday greeting that can be linked to or embedded. You can also record a holiday message with a computer microphone, which is particularly useful for ELL’s.
I’m adding it to The Best Places To Learn About Christmas, Hanukkah, & Kwanzaa.
