Morchaint, I had problems with getting an avatar uploaded, too, but mostly because of the requirements. They're far below that of most forums, but considering this is on David's personal webspace, I full see the reasoning for it.
I just uploaded my avatar to one of my many photobucket accounts, and linked directly to it.
I am me; I am I.
I am alive; I am existent.
I am sentient; I am human.
I am separated; I am amalgamated.
I alone am me, but I, too, am others.
I am but me, alone with everyone together.
I am I; I am me.
