I read Richard Byrne's blog every day. Free Technology for Teachers never fails to offer up good resources, good advice, and good tutorials. For example, here are two recent posts worth reading, if you haven't already...
Scrumblr - a site for sharing online sticky notes. Like Wallwisher and Corkboard.me, Scrumblr is an easy to use tool with great application for classrooms and any groups that need to share bits of information.
And if you have a blog - and who among us doesn't these days - you should back it up! Here, Richard gives step-by-step instructions for backing up your blog on Blogger, Edublogs and WordPress.
And stick Free Technology for Teachers in your RSS feed. You'll be happy you did!
