Hello homershines,

• Is there a manual explaining the process of developing or editing themes/templates?

A docu for editing does not exist at the moment. However, it's simple HTML.

Layout customization
phpSQLiteCMS uses PHP templates to display the pages (preferable with
alternative syntax). The templates are stored in the subdirectory templates.
You can specify the template in the page properties when editing or
creating a page. The default template is default.tpl.

• Can the new CKedit be use in place fckedit?

No. I tested a few days ago, it's not possible.

• Can the formmailer easily be tweaked into a survey/quiz?

No, there must be a php-function for that. A tutorial how to do that:

• Can news be categorized?

Not at the moment. But I'm working on a hack.

• Can other php or ajax scripts be used in phpsqlitecms?

See 2 questions above.

• Can audio files be played in phpsqlitecms?

Yes, with FLV-Player. Quote from <http://phpsqlitecms.net/documentation>:

Photo galleries can also contain *.swf films (with the JW FLV Player
stored in cms/modules/mediaplayer/mediaplayer.swf you can even
display *.flv films). Note that the thumnails must always be
images (JPG, PNG or GIF) (demo).

At the moment I'm working on a BBCode-Hack for easy integration.

Kind regards,
Timo
