@scoop - Are you trying to go directly there from a bookmark? Or do you mean the links from those discussions?
Here is a too-little-publicized recent change to Connect - when you click on a link, it opens in a new window - might be tricky to see if you are on your phone or a tablet.
I did find one broken link in the ABC's, I will try to find out what happened and fix it.
Does this help? If you have more issues, let's try to figure it out (I may be AWOL most of tomorrow - heading out for our day at the Minnesota State Fair with kids and grandkids.)
