Dear Cristina and Greg,
My institution is keen to test your plugin in our Moodle (great news) - I have the documentation and plugin that you provided here www.gmdr.com/MoodleStuff/AlgebraicEquivalentAnswerMoodleUpdate.zip.
However the documentation says it was last tested with version 2.2, and we are now on 2.8 and soon to be moving to 2.9 or 3.0. Do you have a later version of your plugin or should we test this one?
I would be delighted to see this implemented, and it would be a pity if it did not work because of the Moodle version
Thanks for your work!
