SharePoint Community Kit announcement
Check out the link below for information on something called Community Kit for Sharepoint (CKS) v2. This link is from the The official blog of the SharePoint Product Group so you may want to make it a favorite for future reference. The CKS incorporates the following tools: Enhanced Blog Edition Beta 1, Enhanced Wiki Edition Alpha, & ChatterBox AJAX Beta. Each of these tools is apparently designed to help you enhance and extend the functionality of the corresponding built-in features in Windows SharePoint Services 3.0 (e.g. the Enhanced Blog Edition for the WSS Blog feature and the Enhanced Wiki Edition for the Wiki feature) as well something called Chatterbox to enhance the chat functionality.
