WYSIWYG.txt
First pick an editor. PhpWebSite supports the following:
FCKeditor - http://www.fckeditor.net/
TinyMCE - http://tinymce.moxiecode.com/
HtmlArea - http://www.htmlarea.com/ (discontinued)
Get the tarball/zip and decompress them into the appropiate
javascript/editor directory.
To enable the wysiwyg editor go into your config/core/config.php file
and look for:
define('USE_WYSIWYG_EDITOR', FALSE);
define('DEFAULT_EDITOR_TOOL', '');
Set the first define to TRUE.
Set the second define to the name of the directory where your wysiwyg
is untarred/unzipped.
