Now you know ^^
For example I've submit this photo to "ElderScrolls-Skyrim" group on DA. There are a LOT'S of different others group as "world cosplay", "lady cosplay", "skyrim group",..... this is for sure the best way to have lot's of comments !
You just have to go on "Featured in Groups" and "Submit to a Group" write the name of the group and here we go !
P.S: I've seen you're canadian..... so maybe you talked french ? Because I'm french ^^
