I've been busy :)
I hammered out more code for the backend and finally added some user handling and security (yes, it's gone all this time with no security it all.. smart, eh?). The next step is to get the UI complete as it still has some rather ugly parts.
I've also added links to the AlphaFilter() AlphaFiles that I've written, as well as an RSS feed of the most recent ones written. The articles I've written are very simple concepts; but hey, I know how it is to want info on one particular concept and never finding it. My next AlphaFile will be on authoring a plugin architecture, which is leaps and bounds beyond the simple concepts I've written on.
I'm going to spend the weekend rewriting the code for the site. The code for the XAdmin is concise and orderly; the code for the main site is, well, not. So if the site's down for a while, you'll know why.
