Online whiteboard for classes

Hi everyone,

I've just posted in French a short message, but I think I'd better write it in English as well. I'm using a free online whiteboard for my lessons called idroo, which I recommend as it allows you and your students to write and draw and for everyone to see (just need to register and send them the link of the whiteboard you'll create for them. After they've also registered, they'll be able to use it).
There's also the possibility to save the whiteboard as a PDF, very useful when you've written a lot of interesting stuff, and you'd like your students to have it!
You can create as many whiteboards as you have classes. They don't disappear from one login to the other, and save the information you had written.
I hope it will help you.
Here is the link:

If you have any other tips for teaching online, I'd be happy to hear about them!
