Thanks for the fast replies!
Could you guys point me to a kind of Editing “PHP Stuff For Dummies” — I’m embarrassed to say that I really don’t even know what all that code is in those files — what language it is and all that. I mean I’ve been a pretty savvy user of all manner of software for years but never gotten under the hood. But I’m willing to attack that steep learning curve because I dig it! Where do I start?
