I just found a couple of new alternatives for those of you wanting/needing to use a website to build your video (rather than a program installed on the computer). This is a good alternative for those of you using lab computers, as you don’t have to worry about the “right” lab, with the software, being available. Let me know how these work for you, and if you hit any problems?
Here is a list of a bunch more!

If you want, google “browser-based movie-making” (or movie maker) and you’ll find more.
