Just installed and activated Akismet. The Manage-->Akismet Spam says there are 290 spam comments, like this:
You can delete all of the spam from your database with a single click. This operation cannot be undone, so you may wish to check to ensure that no legitimate comments got through first. Spam is automattically deleted after 15 days, so donâ€™t sweat it. There are currently 290 comments identified as spam. [Delete all button]
Last 15 days
These are the latest comments identified as spam by Akismet. If you see any mistakes, simple mark the comment as "not spam" and Akismet will learn from the submission. If you wish to recover a comment from spam, simply select the comment, and click Not Spam. After 15 days we clean out the junk for you.
Then it shows me 55 comments. And there's no apparent way to view the other 245. So how am I supposed to "check to ensure that no legitimate comments got through first"?
