Sitenotice: 11/29/2018: The wiki is back. It turns out, some anti-virus product on my web server had an issue with the latest version of PHP. My server techs have resolved this issue, and things should be working again. During the investigation, I did restore to a backup from September. There is a chance that any changes done since then were lost, but I do not recall any edits. --OS-9 Al

8/30/2016: Massive re-work is being done on the InfoBox Templates. Read that page to keep up with the plan for that, and adding better keyword tags (categories) to all the pages. --OS-9 Al (talk) 15:28, 31 August 2016 (CDT)
