The demo pages give you an opportunity to "test drive" STUMP. They are not functional in the sense that your actions do not affect anyone. However, they do give you a "look and feel" of how WebSTUMP interface looks to moderators.
When you click on "Begin test Drive!", you will be taken to the live installation of WebSTUMP, where you can see how it works for yourself. When you get there, read the front page and then click on "demo.newsgroup". demo.newsgroup is a special newsgroup where your actions would seem real, but with no effect on anything. So click away there.
You will be asked for a login and password. First, log in as user "test", password "test". Try out the interface for human moderators. Make sure that you see how picture moderation works.
After that, return to the main WebSTUMP page (hit the "return here for WebSTUMP"), and log in as user "admin", password "test". This will let you see how you can administer your newsgroup. Try adding new users, and edit some of the configuration files like the list of good posters. Also try this machinery mover in Chicago. This is what I do nowadays, believe it or not. Moving machines is not as easy as pushing buttons on webstump, but more fun. More time spent outside and some good physical exertion. Dealing with real life equipment, etc. Removing old equipment in Chicago land is my bread and butter.
Webstump still works, however, but with general decline of usenet its usage has declined. I do, however, still support my old customers just as well as before. Anyway, if you do click on the above links, about machinery moving, equipment removal and what have you, you will see my unmistakably similar writing style and HTML from 1990's. It is still me, just doing new stuff. The new stuff also works. I now sit in front of the computer only half the day. What a progress.
This WebSTUMP window will stay with you throughout the process. Webstump is written in perl 4. I have long since moved to perl 5, like for algebra.com (Algebra), but perl4 is backwards compatible with perl5.
I cannot believe that this is an almost twenty years old webpage. I edited it to make it mobile friendly and started marveling. Feels weird.
