Hi! Well, first of all, thank you for inviting me to this group! Second - Members can't submit their art, you need to fix those options in Administrator log. I hope that it's helpful!
E, pricam na srpskom posto sad videh da si iz Srbije! CX Treba da dozvolis za ostale foldere, a da prekines dozvolu za Featured folder da clanovi stavljaju radove. Za sad samo moze u Featured folder-u da se stvaljaju radovi!
