Now you will now why I haven’t updated the tutorials in the last few weeks. We just shipped the Best Practices Analyzer, and now it is available for down load. You use the Analyzer to check your BTS installation and configuration against our list of best practices. Each issue the analyzer reports is supported by a brief article outlining how to fix and where to look for more information.
