New (to me) Screencasting Tool!

Here's a screencast that I made to help our web2.0 cohort members who are doing the SLL2.0 course this fall with uploading their avatars to their blogs. Screencast-o-matic is a very easy and free tool that I will use again to create screencasts. I'm thinking of making tutorials for my teachers/students on it. Great for teaching new students how to use our PAC, making booklists on our PACs, etc. On Screencast-o-matic, the videos can remain on their site (of course, it's blocked at our school), or you can download it, embed it, etc. Very slick.

I have tried repeatedly to upload it to Teacher Tube, but I'm not having any luck. It keeps getting stuck and times out on the upload. So I'm embedding it here, although that's probably not a long term solution because it's 4 min long and 42MB. I'm learning though--this is a first effort. Any wisdom out there about using Teacher Tube, making screencasts, etc.?
