My JUG web site is hosted by google apps as a google site
(
http://sites.google.com/a/breizhjug.org/home)
The google sites editor is nice for quick updates with no knoladge of HTML, but is limited and removes any <script> or <iframe> element that would be required to include a custom content. The only way to include some mashup-content is to use a google widget.
For this reason, and to also support other publishing services (iGoogle, blogger ...) it would be nice to have Parleys Share packaged as a google widget.
