SharePoint offers powerful ways to retrieve and render information. Unfortunately, advanced customizations are often out of reach for end users, sometimes because they involve advanced techniques, or, most often, just because people are not aware of such capabilities.
The purpose of the SharePoint User Toolkit is to facilitate this discovery process. In a matter of minutes, and end user with site owner permissions can implement a color-coded calendar, a tabbed interface, countdowns, or list rollups.
Note that the solutions are provided for demo purposes. If you consider them for large scale deployments, be sure to review the implications in terms of maintenance and upgradability.
