You have a capitol idea there and I too believe there would be keen interest. Now if I can figure out how to create a ping list. Let's do it!
I think a ping list is just a text file that you create in an application such as Notepad or MS Word. You just type in all the user names on the ping list with a semicolon in between, just as they're listed in the "To:" line on replies to posts. Then open the file, click on page 1 and type Ctrl + A simultaneously to select the entire ping list. Then you paste it into the reply with a Ctrl + V. Well you probably knew all of that but that's all there is to a ping list as far as I know...lol.
