Okay, I've tinkered with the group settings, and turns out member requests were turned off for some reason. It should be all fixed now, so if you tried to join, and couldn't, give it a try and it should work for you.
If not, please contact DTaina and me Sironae on our profiles to get us to invite you, cos if you comment on here, we don't know about it, cos it doesn't show up in our main inbox. I only found out that people had commented cos I decided to check the group inbox.
Anyway, join requests should be open. So give it a shot.
And too all who are considering featuring some of your pictures in this group, I have made it so that you only require one vote to get your picture in the group ^^ Enjoy.
