I posted about Screentoaster last month.

It’s a super easy web application to create online screencasts, and a sure bet for inclusion into my The Best Sites To Practice Speaking English list once it becomes open to the public.

Today it unveiled a number of new features that makes it even more attractive, and provided the TechCrunch blog  with 500 free invitations.  If you go to that blog, you’ll get instructions on how you can immediately sign-up for the service.
