(Unfortunately you can't download an installable build yet due to Apple's restrictions on third-party app installation. If anybody's interested in testing, I'll continue to do some experimenting on this on the weekends and could make builds available via TestFlight. Let me know!) -- brion _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
