does anyone know if there is a widget existing or planned which shows the blog’s top commentators? I know there are some for the free WordPress blogs, but I haven’t found any official solution for WordPress.com. Would be a great feature for motivating readers to take part in a discussion.
If you have downloaded software from wordpress. org then you are posting in the wrong forum. We run on different software and in that case you need to post here http://wordpress.org/support
At wordpress. com there is Recent Comments widget that is not available in the widgets for wordpress.org installs. At wordpress.com there isn’t a widget planned for Top Commentators that we volunteers are aware of.
If you have a wordpress.com hosted blog you can request one by contacting staff during support hours http://wordpress.com/contact-support/ And in the meanwhile, you could use a text widget and design it to include the linked names of your Top Commentators.
