I saw that to the right of the "tools" link was shown a number in a yellow background, but when I clicked on it, I have been taken to the flags page, and the page was empty.
What does that number mean? I thought it could mean the number of flagged posts, but clearly it is not so.
As the number keeps to grow (I now see 12), I guess it is the number of flags still not processed, including the ones I cannot handle. If that is the case, then the counter should not count those flags.
