Yeah… Discussions is just how I do it, I wanted to organize 'Squid Party' in an out-of-the-way spot, just for people who wanted to read it.
Using Play Journal and "commenting" more art under your post is a good idea, but in neither Journal nor Discussions does a comment add onto your list of Posts. :\
I say, try it your way! If it works out, great! :)
