This is a great idea.... but of course many teachers won't have time post anything - maybe we'll get lost of spikes of posts in holidays!
You might like my last but one post on why I'm quitting teaching (UK focus) it's not heartening reading, but honest!
I am following and look forward to reading it! Check out my blog, too. I am a soon to be retiring teacher writing my second book, this one about a teacher who quits during the state testing. You may enjoy. Blessings!
