How can we make wikis as common as email?

Using wiki as replacement for email communication during collaboration process is indeed a challenge.
Best practices *must* be established. _Seems like there is no natural agreement on this_.


Twiki markup test:

The list:
* List item 1.
* List item 2.
* Internal list 1.
* Internal list 2.



So twiki markup doesn't work.

What about inline HTML?

<b>This is bold.</b>

<div style="font-size: large;">

This is larger.

Unfortunately that also doesn't work.

</div>
