Some actions, depending on their nature, may have quite a large impact on your account, or the site which you're managing.

In these cases, we throw up a confirmation window to ask you to confirm that you really do in-fact want to perform the action. (See the screenshot below)

In this case, we ask you to type the actual word "CONFIRM" in capital letters.  This is more reliable than a window that says something like:

"Do you really want to do this?  Yes.  No."... and you accidentally click the wrong one.

When prompted, simply type the word:  CONFIRM

...and click OK to proceed.
