Editing has never been open to nonregistered users. The current password protection is for access to even see the Wikis. Yet another example of a few screwing things up for everyone. I don't know if they were trying to rip them or trying to hack them, but they were using near 100% CPU usage, which was dragging the whole site down.
I am hoping that this is just temporary and that I can eventually open it up to public access for viewing again. As to moving them, I have enough work and time in them that I am a bit loath to lose control of them and some things need FTP and cPanel access.
If you are going to add links, don't forget the AGI Wiki.
