me vs. google sites

Oh my god! I just wanted a tiny little To-Do list. Maintainable and editable like a wiki using wiki-markup (or something similar).

I tried...
I tried harder...
I fought...
...
I lost... :(

Although Google says "Erstellen Sie Websites und sichere Gruppen-Wikis" I neither managed to set up a simple (and more-or-less eye-friendly) website nor to set up a simple wiki. Grrrrrrrr!
