As far as i know its pretty easy to add to collections. There should be a thing on the submission after you submit it (On the page when its all done not during the process) but they should probably make it a lot more easier at some point.

I think a better question is WHY did you join here? I only did it just to test the website out or for "shits and giggles". I dont plan to come here often unless FA goes down the drain or something.
