I don't want to spam and I don't want to step on any toes, ESPECIALLY not those of Mr. MaryLou, but I would be a bad, bad marketer if I didn't pop in to mention DragonList. I built DragonList because none of the commercially available scripts did exactly what I wanted. I personally think it's one of the friendliest linklist scripts out there, but of course I'm biased.
More info and a demo are available
here. We're still getting our billing system set up, so the script is not officially released yet, but it IS available for purchase. Oh, and the demo is not the most recent version, but it's fairly representative.
I use the script to run
XXX Good Stuff.
Now I feel like a dirty, spamming whore. Off to take a shower...
