The forum is becoming an easter egg hunt.
The hunt began on my iPhone:
Notice the Mind Mapping thread with 117 replies!
I select it, but notice it's quite old and no comments yet.
But that would be a mistake.
The trick is to turn the screen horizontal. The individual pages will show up (only as horiz). And, don't select page 1 (no comments, remember). Start with page 2 (or later).
I didn't tag this … the menu has a gazillion mixed entries.
