Just FYI - for the AutoAction > Action tab, I noticed that [cb:parse function="getContext" class="var2" /] would return a full url for Replies, but would not include the https:// for comments. I think this has to do with it being an Article feed.
So I changed it to the following, which effectively takes the user to the Recent Activity feed URL:
https://[root url]/[RecentActivity]/func=show&id=[var2_id]
Thanks!
