Hi there, I don't know what went wrong, so I'll just type out what I did.
1) While logged in, I added a comment. This has accurate gravatar.
2) I logged out of my wordpress account.
3) I go back to front page, and I still see I have the "clear" option. This option should be just for admin as per my settings. Why is it shown to a logged out user?
4) I added a comment. There is no gravatar (because I logged out?). Shouldn't I be asked to log in instead?
