== Sandbox categories == 

 I found the categories on the listing of unparented categories.  So that's how I came to them.  As for them being in your user space, they are not.  That's a key part of the situation.  Categories are always in the main user space.  The "Category:" in front defines that.  If you look one or two submissions below yours you'll see me submitting a couple of categories used by others to organize their subpages, and I'm a little more detailed about wanting these type of categories to go.  The comments are, in the end, just my opinions.  CFD is a vote, and I've lost submission votes a number of times, showing that my opinion is not always in line with conscensous.  So be it. 

 In the end though, I did make one big mistake.  I indeed should have informed you that your categoies were being put up for CFD.  I apologize for not doing so.
