Author pictures, as you can obviously see, are back again. I had to rewrite the code from scratch and am testing them in the blog posts only.
If I feel confident in the code, user avatars will come back in the comments but a two restrictions: 1) pics can be no bigger than 3kb in size, 2) they must be exactly 85 pixels high if you don't want them to appear stretched out.
Private messaging is working again also.
