I've just completed the pre 1.0 release of my text ads system, and I've put it into testing on one my sites, nancies.org. I had been looking at Text Ads (that's the name of the program), but it's much too bulky for me...plus, it's really going in the wrong direction. I wanted something very, very simple, with PayPal integration, written in PHP, with no accounts system, no method for users to track ad performance...just a basic system good for your average small site. I've shaken out some bugs in the past 12 hours, and it's proven to be a pretty popular feature. I start spring semester on Monday, so hopefully I'll have time tonight to package this up and make a 1.0 pre release out of it.
