Wow, it's been about two weeks since my last post. I have been quite busy in the last month finishing up a custom social network that I developed in CakePHP.
Fahad the author of Croogo has added some great new functionality to Croogo especially when it comes to extending the system and creating your own plugins/hooks. I will be writing up some tutorials once the hook system is complete (hopefully in the next few days).
To test out the new plugin/hook system I developed a Tagcloud plugin with it's own admin panel that will allow you to add a tagcloud to your Croogo install. Check out the plugin page for more details and to download.
