Hi Penguinpc!
First off, I would also like to say welcome back to the teaching profession! WBT has made a huge difference in my teaching style and the way my classroom runs. I agree with Heather and Rebecca that WBT would be very beneficial to you as a possible cadidate and also as a sub. I had subs last year that used it in my classroom through my instructions and utilizing class leaders, and they were so on board after that! Stay on the website and the forum and you'll find lots of great tips! Good luck and keep us posted!
Thanks,
Staci Glass
