We have recently introduced some useful features in our comments system which allows you to comment on guides or blog posts. First of all there is now a comment's control panel which can be found here and which allows you to see all the comments you have made. In the same page you can control two of the new features, comments subscriptions (that gets you notified when a new comment is made in an article you have selected) and Favorites which is a list where you can add your favorite articles for easy later access.
Besides that, you can now add an article to a social bookmark site (Facebook, del.icio.us, Digg, StumbleUpon to name a few) easily from the article's page or email it to a friend. There are also some comments specific improvements like comment voting, report comments to the admin and Trackback URL that you can use to link us with your blog. We hope you enjoy using these new features.
