Think we're gonna put this in.

Two other accessibility questions regarding your site:
1) The acronyms, do you add them manually or by using a module?
2) The external link image, do you put the class for that in the link manually? I think I've seen some script about that earlier.
Thanks!
EDIT: Found the post about the external links. We'll probably add this to the core as well, maybe as part of the cms_selflink tag. Thanks for the tips!
