[pmwiki-users] Tagger

[Brent Zupp]

Wonderful use of Page Variables, Kathryn. Very clever.

I'll have to play with it. I use categories extensively, so I'll need to
figure out if tagger can play nice with what I already have in place--but
regardless, thanks for sharing this recipe. Really cool idea and execution.

Best,
Brent
