This is my first attempt at writing a plugin for WordPress so I'm soliciting feedback on the concept before releasing it. The concept somewhat follows the Get Recent Comments plugin with the difference being that the comments dispalyed in the sidebar are actually references to other sites in which you have commented. For example, if you run bobsblog and post a comment on stevesblog, a reference to the post on stevesblog would show up on bobsblog.
To work, post a comment on someone else's blog and tack on a variable to your site address, ie. http://dailydoseofdave.net/?t=dpb.
The plugin then detects that variable, checks the value against a list of authorized users and captures the title/URL of the referring page. It only does this once per URL/user.
Each entry is then held for Moderation where it can be Approved, Edited, or Deleted.
There is a working version on my site, Daily Dose of Dave
I appreciate the comments and suggestions from everyone. Feel free to be as harsh or supportive as you feel necessary.
