In pset6the pset6 specification, just after the last inline youtube video and the info about Valgrind, there is a link to cs50.net/discuss (just after the info about valgrind, after the last inline youtube video). WhenWhen I click it, it redirects to the HUID/XID login screen. ClearlyClearly, that's not accessible to most edX students. Perhaps, so why is the link provided in the pset6 specification? Is this a mistake left over from the College version of the pset? If not, what's up?
