They were there, I tell you!

They were boxes that held a list of the forums. These would appear when one logged on the site, or went to any thread. You could scroll down in the "box".

When I tried to start a new topic (about the boxes!), they would appear, and in addition to the "white box" to type in the text, another white box would appear below, labelled "shortcuts".

Same with an ordinary (not "quick") reply. Then they would appear in a section labelled "Interactive". The same two white boxes would appear. But whenever I tried to post a new topic, or a reply, it would not post at all. Then I tried the Quick Reply here in Eric's post, and it worked. Then they were gone!

It was some Yuku feature, thankfully very short-lived.
