Do you know Russel Stannard's site, Teacher Training Videos? Russel is an ESL lecturer with a passion for ICT and generously makes videos about all sorts of tools and how to use them. You'll find tutorials about blogging, wikis, virtual learning environments like noodle, smart boards, as well as smaller tools like Jing and Sketchcast. If you're a beginner, the tutorials are perfect, they're detailed and clear.
Glad you like them too, Megan!
