I'm with a job that I was asked for a platform in moodle. I have to make a plugin to send mass emails to all the students who failed the course ... What if, never in my life touch moodle but still accept the work ... The first thing I did was download moodle in my machine to work ... then I started to download some plugins such as Quick Mail to see how it works. But I can not move from here anymore .. when I install the plugin I can not find where to use it, in all the tutorials and documentation that I saw I should appear as a block on the right of my machine .. any help or advice? I'm using moodle 3.5
