Traffic on these forums has dropped WAY off since I first visited. I'm sure there a few of us around that would be amenable to updating the basic code, maybe writing a simple install/user guide (readme). I think the direction of websites has changed, and collections of links are no longer what people "do". The power of Links2 is that, with simple changes, it can perform a vast array of tasks.
One of my projects has it being used as a membership directory, with many custom fields, photo uploads, links to get maps to members, and more. That install builds PHP pages, which are password-protected by a PHP script.
Another one displays a fellows' collection of police patches, with thumbnails linked to full-screen images. (There's a whole culture out there that's into collecting and trading them.)
So, I again suggest to the folks at GT (are you listening?) that Links2 be made Open Source, or at least reduced in price to $50 or less.
The basic idea behind open source is very simple: When programmers can read, redistribute, and modify the source code for a piece of software, the software evolves. People improve it, people adapt it, people fix bugs. And this can happen at a speed that, if one is used to the slow pace of conventional software development, seems astonishing.
