Introduction

Problem Statement

Online peer-review systems are now in common use in higher education. They free the instructor and course staff from having to provide personally all the feedback that students receive on their work. However, if we want to assure that all students receive competent feedback, or even use peer assigned grades, we need a way to judge which peer reviewers are most credible.

Issues to be fixed

Fix Issue #311: when one respond to an advertisement, (s)he should only be able to respond once. When a team advertises for new members, someone who responds to an ad should only be allowed to respond once. Currently, after someone responds to an ad, they can respond again an unlimited number of times.

Fix Issue #227 : if user A got a topic and user B got no topic, then A join B’s team, A’s topic be dropped and A and B end up with a new team with no topic. This issue should be handle carefully because we cannot simply add B to A’s team (imagine, if A has teammate X and B has teammate Y...). One of a potential fix is that, for assignment w/ topics, one cannot not post an ad unless (s)he holds a topic, similarly, one cannot sent invitations unless (s)he holds a topic.
