This is how you moderate comments with WordPress this far: First you receive an email from WordPress notifying about a new comment (whoohoo!) Eagerly, you click the “Approve it” link. A new tab opens with a form asking you to log into the administrator area. You input the username and that long long password, click “Log Me In.” There, you are welcomed with a silly “Are you sure?” confirmation message and two buttons: “Yes I’m sooooo sure” and “No I’m not sure at all, my $200 mouse was just malfunctioning.”
Ever felt that it’s a little too much? Well, if you are that lazy (just like I am), then Lazy Moderator is just for you! Now the notification email will be appended with real “one-click” links to help you moderate the comment with just, well, one click. Yes, one click and it’s done. No login. No confirmation. No hassles. No shit.
