eduClipper, the popular bookmarking tool for teachers and students, has another feature for teachers. Teachers can now use eduClipper to create assignment portfolios. Assignment portfolios allow you to assign projects or tasks to students. You can assign a start and end date for each project. Within the assignment portfolio you can include a project / task description, links to materials, and project files such as rubrics that you either upload as PDFs or insert from Google Drive. Students submit their completed assignments through the portfolio where you can then offer feedback in the forms of text, audio, or video comments. The video below provides an overview of all of the options in eduClipper assignment portfolios.

Applications for Education
Through eduClipper assignment portfolios you might be able to accomplish two goals at once; distributing assignments and creating portfolios of your students' best work. The audio and video feedback options could also be a time-saver for you when you're assessing a lot of assignments at once.
Disclosure: I have a very very small equity stake in eduClipper.
