I developed EasyMark for my own use while teaching. The univeristy where I worked had a Learning Management System, but I found it big, complex and hard to use... at least for what I needed. EasyMark was designed to be easy to use. It does one thing, and that's all: generate assignments with rubrics.
EasyMark is free to use, with limitations. You can raise the ceiling on those limitations by upgrading your account to a paid level. Hey, it's only $50 per year, it will help me develop EasyMark and will make your assignment creation and marking a whole lot easier!
