Something that isn't clear to me is what posting patterns I should follow. Just an example: if I make a thread under Paintings just to introduce myself and show some of my stuff, is that also where I should post WIPs for critique, or should I make a new thread for that? Or should I be posting in a critiquer's hello thread to do this? More generally, I'd feel less reluctant to post if I knew exactly where the post I intended to make belongs, because I don't want to clog up forums with too many threads in the long term, nor do I want to inadvertently hijack threads.
