Hi, thank you for the wonderful new editor! I am wondering if there exists a tutorial somewhere that we can share with our members?

Very good question. In the standard design view there will probably be little need for a tutorial, as most of the icons are very simple. I.E. bold, italic, underline, insert image, etc. If a Classmate clicks the source button, now they're in a whole new world of html code. For that I recommend you link them to a free html tutorial such as this one. It should be noted that most Classmates probably wouldn't (or shouldn't) click on the Source button. That's really for advanced users who might be trying to drop in videos or slideshows or whatever else. For the most part, typical Classmates will just be typing messages and maybe uploading an image here or there, all of which is very simple now.
