Okay, I am not sure how your computer may run, so I don't claim to be an expert...If you head to the group itself, when the page fully loads, a dark blue box should appear and that should have several icons in it. One of the icons should have the choice that allows you to join. Just click on that and within a few minutes (and hopefully without this site's usual problems...) you'll be able to submit art to the group's gallery! ^ ^;;
