The Halls are meant to be halls only. So no comments here. The comments are held in the comments section, the Walls.
The members who have a Hall, should include a Wall for comments in the rightful section, and provide a link from the Hall to the Wall, and vice versa.
That's all.
You can do anything here, post your creations, write random things. If ever people take graphics from a hall, make SURE that there will be credits to THAT wall, and not just the forum itself.
