It seems that the KA devs have taken a massive task upon themselves and in the process have taken down two parts of the site critical to the KACP community.
While the entire discussion platform still exists like it did before, I have found that posts made in the Tips & Thanks now default to the Questions tab when redirected to a specific post (qa_expand_key). Additionally, some comments have gone missing entirely. Please be sure to let me know if this is a user error rather than a site-wide issue (although I doubt it considering other posts made on the matter).
While this may be frustrating as a community, we shall wait patiently and cooperatively until these issues are fixed, :). Best of luck to the KA devs!
