A 1.16 compatible branch already exists at /branches/REL1_16/extensions/UsabilityInitiative/. Could that not be updated instead?
Yes! Didn't see that there.. Yes it can be.. I will remove this. Thanks for the heads up.
Well, i won't delete it yet, because there are patches in branches/usability-initiative-1_16/ that need to be merged into /branches/REL1_16/extensions/UsabilityInitiative/ and probably /branches/wmf/1_16wmf4/extensions/UsabilityInitiative/
