Q & A (hopefully) on Instructables Contest Ideas Answered

I have an idea for a contest but I don't know where to post it.  If anybody knows how please let me know or post it wherever themselves.  I would also appreciate it if all similar posts be connected.                                                                                                                                 The Idea is for a Shelving contest, due to the fact that people have lots of cool ideas that are spread all over and there is no way to be able to see them.
