Plugin: EditComments
Author: Jon Daley
Release Date: 2006/12/03
Version: 1.2

This plugin allows the blog owner to edit comments and trackbacks
via the administration interface to fix typos, etc.

Install:
1. Copy the files into your plugin directory like any other plugin.

Use:
1. Go to Manage Posts -> Posts and click on a comment in the "CM"
field.  (or Manage -> Comments for all comments)
2. On the edit comments page, there is now a link on the far right
   to edit the actual comment.
3. Click that button, and you should be able to see the topic, text,
   username, url, etc. to manually edit.
   
(editing trackbacks works exactly the same way)
