There's nothing wrong with the C2 Wiki and there never was. My ISP had been blocked in a group with other IPs that Ward Cunningham had discovered were huge spam sources.
The Triumvirate project is plodding right along at a snail's pace. I have settled on a mechanism for doing the PHP interaction with the user, at any rate. Now I have a scheme by which I create a before script, an after script, and an HTML page to present to the user. The before script sets up all the data access and looks up everything that the HTML page needs to show the user. The HTML page formats everything and puts it into a source form that is easily understood by even the script challenged. (Yes, I know the HTML could go right into the PHP setup script, but I wanted to separate things for a variety of reasons -- modularity being one of them.) The after-action script processes and publishes the results of the decisions the user makes on the HTML page. If there is a complicated format to the results then all that can go on to a second HTML page containing all the formatting.
The Triumvirate code itself hasn't gone anywhere because I am still in discovery about how the simplest user operations are going to happen. It would be nice if I had some help here, but I don't know anybody who deals with this web application junk and nobody I know is interested in farting around with it. [sigh] Oh, well.
