Even though I'm a longtime fan and frequent user of Wikipedia, I didn't really know much about wikis until doing all the wiki readings. Unfortunately, I still haven't been able to watch the video, since our two antique PC's seem to have all kinds of necessary stuff disabled, are running low on memory, or whatever. But I will remedy that soon...Meanwhile, I learned a lot from reading some of the wikis of other library systems. For instance, one internal library staff blog explains how to embed almost anything into your website (or blog, presumably).
Anyway, I went to the SPL Wiki Sandbox last night and played around, having fun, just as the directions said. Got a little carried away. Later, I realized I had done a bit more than edit, maybe. And a voice in my head said, "Uh-oh." And then, "Fix it!" (Yes, there is a voice or two in my head some days...) So I went back to the sandbox this morning and tried to straighten up for the next kids/editors.
