I just stumbled over this page in the Stack Exchange dropdown (top left corner).
cs50 - For students of HarvardX CS50x: Introduction to Computer Science
When I click on it I get the following message:
Warning: this site is currently in private beta for at least a few more days.
To log in, you must have commited to the Area 51 site proposal and received the invitation email. Click the invitation link in the email to log in!
However, the page on Area 51 does not exist, so it's impossible to get any further information.
So, what is going on? Apparently this is a private site for Harvard students?
I don't have a problem with that in general, but I wonder
- a) Why is it part of the Stack Exchange family if it is a private site?
- b) Why does it show up for me under Stack Exchange sites at all if it won't even let me have read access to it?
It seems that there are several of those sites, for example edx-cs-169-1x.
Is this some sort of pilot project?
