FOSS gamedev and creative worlds

I've been having some trouble with the catacha on the wiki.

Even when I correctly identify the cat pictures, I still can't seem to post external links using the save page button. Am I missing something or does anyone else have this problem?

Ubuntu 12.04
Firefox 13

That's the wiki's fault, not yours. ;)
Try posting the external link with a space, like this, and tell the users to remove the space:
http ://google.com

That lets me add links, but it sure isn''t pretty.
