OT: best FOSS wiki for this classroom scenario?

[Liam Proven]

Whhops, sorry, I accidentally sent that prematurely. I was going to say that

Oddly, and I don't know why, I've found multiple FOSS 2-pane or
extrinsic outliners:

• Leo, as you said
• KJots: https://userbase.kde.org/KJots
• TreeLine: http://treeline.bellz.org/index.html
• WikidPad: http://wikidpad.sourceforge.net/

Others bemoan the lack, too -- http://outliners.scripting.com/

But I've not found a good single-pane / intrinsic one.
