So currently, the journals
mainly run within Wikiversity (with a
proposal to start a new sister project). It would only be the
test wiki that would be sensible to run through wikispore to develop new features currently impossible in wikiversity (see
technical wishlist). As far as I know, the current test wiki doesn't have any backups, or monitoring. The domain name isn't really important for the test wiki, since it's just a feature development and testing. The factors that would probably be most useful would be a support community for developing new features, and support and advice on then implementing them on a WMF wiki. Most of the participants in the WikiJournals do not have technical mediawiki knowledge, and are more focused on content creation, so having help on that side of things would be a huge benefit.
