Great Plugin: Edit Comments
There’s more than one comment out there to let your commenters edit the comments they’ve posted. I originally tried the one by Jalenack that featured an Ajax countdown. It mysteriously stopped working at some point during my upgrade from 1.x to 2.x of WordPress.
Fortunately, Ronald Huereca came up with an Ajax comment editing plugin that is awesome. Every comment has an "Edit" and "Delete" links at the bottom, accessible to the author of the comment for 90 minutes (you can set the time limit - I don’t want people changing their comments hours after others have replied, so I figure 90 minutes is long enough). The site admin can always see those two links, plus a third that says "Spam". You can set the level of permissions people need to be able to see those links longer than 90 minutes, if you have moderators or a community blog.
Without ever loading another page, you can click on the body of the comment and it forms a window where you can edit. Or you can delete it or label it spam. All fro right there, where you were sitting when you saw the comment gone awry.
