How am I supposed to get a mentor?
There’s a buton called mentorhelp, which is used to ask questions to mentors. Not sure if that works like ahelp, whether if mentors are called through discord. If no one answers over mhelp, you can also ask in Discord in the #mentor-help.
Basically what @Time_URSS said. In the top right under the ‘Mentor’ tab, click Mentorhelp and it honks the online mentors (though the chances of getting a response when AdvilPmSevere and I aren’t on isn’t big), the Mentorwho verb will also tell you all the Mentors online, so if you’re not getting a response, ask in the discord so mentors on mobile can answer too
