I’m glad that you can; unfortunately, I can’t. Where is it on your Users page? I have, on the left side of the page:
Name, First Name, Last Name, Nickname, Display Name Publically As, About Yourself, Personal Options: Use the visual rich text editor.
On the right side of the page:
Contact info, Website, AIM, Yahoo IM, Jabber/Google Talk, the Update Your Password Box, and the update profile button.
That’s it. No API key anywhere.
