As I mentioned in another thread, I was having trouble with billing for my wikidot account.
Well, I posted the same thing over in the larger wikidot help community, and the responses were pretty disturbing. If what they say there is true, then wikidot management has gone "radio silent" to most communication. Supposedly a host of features are broken and not getting fixed. One such bug they mentioned is search functions, which I can corroborate I've noticed being extra buggy lately and often ignoring pages that I know for certain exist (this has happened both here and on another wikidot wiki I work on). Supposedly there are also issues when trying to send invitations to new users — I haven't experienced that personally, but I also haven't had reason to send an invite in a couple years. The "whois database" lists the registry for wikidot.com as expiring on April 28th of this year. I don't want to be alarmist, and I'll freely admit my level of "research" into this is quite limited (and essentially is nothing more than listening to rumors posted in that forum)… but there's a non-zero chance that wikidot could just vanish at the end of April. We might want to consider migrating the site, and that might take some serious man-hours to do.
At the very least, I would encourage my fellow admins to log in to the admin panel and save/download yourself a backup of the wiki.
