@EileenKCarpenter Aha. I did have to close the page. The entire right column disappeared. Thanks.

@ceorl Thanks -- but I had to close the tab and reopen the site for that to appear. It was all gone. Must be a bug.

@Snarkysteff At the top of that farthest right column, you may have to click "Back" a few times to get that panel again. Then click Community Firehose, then move the column where you want it and pin it.
