So, often I am unable to join a group because the requests are closed, and I ask on the front page if the founder needs to know how to fix that. I often get yes.
So, now, I'm tired of explaining it over and over again, and POOF! Thus, this tutorial. Just follow the arrows, and you'll be a genius in no time.
And now, whenever YOU ask that and the answer is yes, feel free to link them this and save your fingers.
