At last I found top commenters widget that is accurate! I was searching for this kind of widget for the past month but haven't found one that satisfy what I really wish for. I know as a blogger it is a must (well at least for me) to give thanks and credit to our visitors/commenters. This one really works for me. Thanks to Mommy Kaye of Wahmholic. Try it! It is the only widget I found that will count comments for the current month. Of course you have to set it monthly..and will count on last 5,000 comments of the Month.
So if you wish to have it in your blog. Just visit the link I give. Wahmaholic. Mommy Kaye explain everything in her blog.
Thanks to PMC Group! Thats where I found this.
