Kristin @ Ladybug's Teacher Files has a TON of useful technology tips for maintaining your blog. She even has video's!
I hope the Clutter-Free Classroom feels the love from me! I about lost my mind when she started posting ideas for themes. I swear I was ready to wake up my husband out of a dead sleep when I saw the post for the
Hollywood Themed Classroom ideas!
Lastly, I obsessively stalk What the Teacher Wants Blog for free downloads and tons of management & organization tips.
