I am back to developing sBlog.Net! It's been a while since I got a chance to work in this project! I have added disqus support to sBlog.Net :) You don't have to go with the native commenting system anymore! Fun, isn't it ? This change only went in to the master branch. You can get it from github here!
First step to use disqus is to get the latest source. Then run the sBlog.Net.DB\v2.0\Update\sblog_02_01.sql on your sBlog.Net database. Now login as the administrator and go to the Settings page. Here you will have the ability to enable the disqus commenting system. Just register with the disqus site by specifying your site name since you need the disqus shortname to finalize the process of enabling the disqus commenting system for your site!
Have fun and happy coding :)
