Joel Oleson has the following to say in his Top 10 and a few "MUST HAVE" Management Tools for WSS v2 & SPS 2003 posting about the tools I've been writing:
Site, Database & User Management
- SharePoint Utility Suite v2.5 – User, Site, & Database Manager & Analyzer
Keith Richie has put in some huge investments to make the life of the IT Pro easier. This is my number 1 tool on the this list of “must haves”. Use it for Sites, Users, and managing databases. Don’t forget to use this to move subsites, My sites, and move users between domains… This stuff is incredible. He’s now working on the next rev of this and other cool stuff. I recommend following his blog.
