I finally got to the point where I wouldn't get errors while trying to make my user theme incorporate the "full update" component (with login~ yay). There's only one problem now; when I USE the theme (actually the user layer), the update component WILL NOT show.
Aahhhhh, save me.
And if it's something completely obvious, I'm going to go poke a needle into a cushion many many times. :/
I think the official consensus is that I am stupid. *baps herself for overlooking simple things and rummages through more tutorials* It's so fun to play with layouts. :p
