    Many thanks for sharing this plugin with the Moodle community.

    I was successfully able to install the plugin and it appears to function as expected. Hence, I am going to approve this plugin.

    I noticed that the copyright in version.php references a previous author. It is preferred that all of the files that you have modified for this plugin have your name listed (or added) as the copyright holder.

    The code check shows:

    The plugin shows 15 errors. What will be the difference between a reviewer and a quest manager then? I study at Drexel University on Media Arts and Design and we are cooperation with Quest and Pimion on that matter. Both of them have created a quest manager team. I had to buy case study on Pimion to see the difference.

    Hi, I've recently installed this plugin and get a conflict.

    The styles.css file has the rule
    div[id*='dme'] {background-image: url([[pix:qtype_easyonewman|me]]);}

    But that selector also finds the background in the group addmembers page, that get filled with methyl groups.

    Just changing the selector to
    #draggable div[id*='dme'] {background-image: url([[pix:qtype_easyonewman|me]]);}

    avoid conflicting issues
