Mschneider:
I get it, even if Llorean didn't. Very good!

I get the occasional "unk(n)own" here and there, which is why it is that I noticed the error(s) in various themes. I don't know very much about coding (and maybe even less about IP3 tags), but thanks in part to the afore-mentioned Llorean, who was kind enough a few days ago to point me in the right direction, I now at least know enough to enable me to fix text problems and the WPS parser issues with time/date display. All my Sansa's themes now display time and date properly, and I even went so far as to slightly modify some to display it in ways that I find more amenable.
Flid, to your suggestion about being "REALLY helpful," I'll see what kind of time I can make once I get out from under some really heavy work-related stuff. I'd have to learn how to re-load them, but that doesn't seem too bad.
One question, though... how do WPS authors feel about someone altering their creations without their knowledge and/or say-so? Is that considered OK? Of course, I feel free to alter my local copies, but the ones on the download server?!?
