I've been testing Portfolium and am about to use it with a group of 29 students.
It's a great tool and I absolutely believe that it will allow the group to leave our college with something of real value.
I know that it's a very recent acquisition so hopefully we'll see some development on simple things that could make a bid difference. For example:
How do idea conversations work in the Canvas Community?
What is the feature development process for Instructure products?
How do I create a new idea conversation in the Canvas Community?
