At the previous meeting of the MediaWiki Architecture Committee (April 20), the members present approved the appointment of Rob Lanphier to the committee.
Rob was the main instigator in the formation of the committee in 2014. Lately he has been taking an active role, chairing the weekly meetings and writing the meeting agenda. In recognition of the excellent work he has been doing, and in the interests of transparency, we decided to formalise his membership.
