Matt,

I use pair for web hosting, and they have v.1.08, which is probably why it didn't like the tree method, right? I asked them to upgrade to the latest, and so I'll get back to it when they finish. (I figured installing a local copy was a bit silly if they already have the module installed, even an older version.) I still don't have a code sample of my regexp implementation, I'll get to it sooner or later. I'll try to give you feedback, if I can figure out what is due to my inexperience and what is not. I look forward to trying this out!

Thanks again,

Mark
