Friki - a Java Wiki

Hi
I am experimenting with Friki. It would be really
great if friki could provide a formatting like bold,
italic, underline and font change as buttons on the top
of the text-area. Simillart to one
http://en.wikipedia.org, check the attachments. When
you go to the editing page you will have all the
options on the top of the text-area. If you would let
me I would liek to contribute this to the Friki code.
As I am currently in the process of adding these
features to Friki.
Thank you
Suman Mummaneni.
