ELMAH: Error Logging Modules and Handlers for ASP.NET is a pretty awesome error logger. I've installed it on a couple sitefinity instances so I figured I'd blog about it to help some others with it.

The amount of controls available on the toolbar is super minimal compaired to what is actually available to the RadEditor. Luckily as always Telerik has make it super easy to expand.

Download the Sitefinity 4.0 Beta now!
Shows you how to have sitefinity 3.x generate a UI for you to pick content
This control is like the one found in the Ajax Control Toolkit, but re-done in jQuery for Sitefinity 3.x
Sitefinity 4 will arrive in 2010, or so I hear...
