Silex : Open Source Flash CMS

Silex is an open source Flash CMS that lets you create flash web sites .

It comes with a WYSIWYG editor and the ability to target different versions of flash – version 7, 8, 9 and 10 are supported.

What I liked about the application is that the site you create can be made SEO-ready with deep links.

Download Silex from : http://sourceforge.net/projects/silex/files/

The installer comes with a set of templates to get you started and additional templates/ themes can be downloaded from http://silex-ria.org/?/themes/

The developer API can be found at http://silex-ria.org/api-v1/

The documentation for Silex can be found at http://silex-ria.org/?/help/#/documentation/home .
I must warn you though; some of the content (tutorials) is still in French. Here is a forum in English that might be of help http://silex.hoyau.info/forum_en/
