If I am not experiencing a problem but only want to share some idea with developers of Coursesites – then too the process is complex. I do not understand anything in software/ hardware and even coursesites I am still figuring out. In this situation I did not want to post to a nerdy community. I prefer email as a means of communicating my ideas to someone who can choose to work on it or. But there are no email ID for this. I wrote to email@example.com (from whois details of site ownership) and CourseSites@blackboard.com & found the twitter handle was dated. But got no auto acknowledgement - I did not need any reply – only a sense that it would reach developers. But as per coursesites link had to learn to open a problem query within coursesites knowing they are limitations. They then was directed to share at this forum.
