I recently wrote a script to query the capabilities of a Tridion content delivery environment. Rather than post it here, I've put it up on Tridion Practice. After all, it's about time "practice" got a bit of love. I think I'll try to get a bit more fresh material up there soon. 

I hope you'll find the script useful. Dare I also hope that some of you might be inspired to contribute something to Tridion Practice? It's always been the intention that we'd try to get contributions from a range of practitioners, so please feel welcome. Cookbook recipes are probably the most prominent part of the site, but the patterns and practices sections are also interesting. Come on down!
