In response to your question, I have added an FAQ describing how to access the WYSIWYG editor:
How do I access the WYSIWYG editor?
To edit your site with the WYSIWYG (what-you-see-is-what-you-get) editor, first log into your control panel. Then click the "file manager" icon.Your web site is in the "public_html" directory. Navigate to the public_html directory by clicking the little folder icon to the left of "public_html". To edit your index.html page, first click the "index.html" file. In the upper right pane you will see the various actions you can perform on this file. You can edit the HTML code directly by selecting "Edit File", or you can use the WYSIWYG editor by selecting "HTML Editor".
Note that the WYSIWYG editor is not supported by all browsers. It is officially supported with Internet Explorer version 6 and higher, and has been reported to work with Mozilla-based browsers such as firefox.
I hope this helps.
