Zoho Wiki allows you to pre-set an editor of your choice too !
You can choose from
Advanced Editor : Features a text editor with a host of tools.
Simple Editor : Basic text editor with only essential options
Text Editor : Allows you to see the HTML code version your page
Zoho
Wiki also provides a Constrained Editor, which allows you to edit each
paragraph individually. To use this feature, move your mouse over a
page. You will find that paragraphs appear selected. Just double click
on the paragraph that you wish to edit and a basic editor opens up with
the text of the respective paragraph within.
As
for the service overall, I like the fact that it is pretty simple to
use and I haven’t had too many difficulties in setting up my wiki.
This must be Zoho Wikis biggest advantage: ease of use. I have been
really impressed and I have recommended it to fellow professionals in
my line of work.
