Jon Udell, in his lates byte article, has documented the Calendar Tag: http://www.byte.com/column/BYT20000121S0001 Of special interest is this quote: But despite the immaturity of Zope and its documentation, I've got to admit I've been bitten by the bug. I'm doing some really useful stuff with the product, and this week I decided it was time to give something back. If the major bottleneck is documentation, why not contribute some of my own? So here's a quick tutorial on Zope's Calendar Tag, which I hope will convey the flavor of Zope programming. Gee Jon, could you have come up with a better phrase than 'bitten by the bug'? ;) -Michel
