One interesting thing is that, when I access that wiki page via the wiki navigation index, I don't see the page you printed, but rather a very much older version. This leads me to believe that you found this page by a
wiki search which found an ancient version of this page.
I'm officially retired, but when I get home tonight, I'll see what I can find & fix, and I'll notify you.
Since I brought up my retirement, I'd like to say to everyone that Beth & Ernst & possibly another have volunteered to step up to become
WikiTeam.MementoDatabase.com, but each of them (of us, as I occasionally do a bit of work) has her/his own limitations in getting much work done on it. In the meantime, the developer has released several new field types, widgets, and other features that have so far remained undocumented send like will continue to do so, making the wiki further obsolete.
Everyone, please consider joining them/us and help us bring the wiki up to date, fix its holes & any errors, and better support new users and those who don't understand JavaScript (or any subset of those things).
Just send a message to WikiTeam at the address above and/or me at my address above and let us know what time you might have available, what aspects you're most knowledgeable of, and what parts of the wiki you'd like initially to address. You'd be very welcome, we'd help you ask along the way, and I'm sure we'd all appreciate it very much.
