That sounds really good, it would make my editors happy, they already know how to use threads.
If you get it cleaned up and release it, I would greatly appreciate it. I would probably use it to publish content on my site which I'm hard at work converting to mambo (which is coming along rather nicely) with the added bonus of being able to discuss all articles and news stories and such. Do you have a link back to the discussion of an article? I will probably add a threads comment box on the article page, and possibly a quick list of the discussion as well, if I get the time.
I've made some modules and a component for mambo as well, but they are probably not interesting to others since they are very specific to my site. I did redo mainbody.php to show the recent articles instead of the news stories published for the front page. And two modules are for listing the latest news instead, in two different ways. Those I could actually modify a bit to make it customizable to list them in different ways (like most viewed and stuff like that) if you're interested.
I will probably also modify my old newsletter script to be a mambo module, but since there already is a module released for that it probably isn't of interest. I also have a small module that lists the info of the latest link added.
The next thing I'm going to do is to add a table for Reviews and corresponding components and modules, because I need extra grade info added.
While waiting for the threads link system add-on I'll probably write a small module to search in Links 2.0 from Gossamer Threads, which is the system I use at the moment, as well as a random link viewer.
