• continuing CiviCRM and internal dashboard work
• examining anti-fraud rules for existing and backup processor
• investigating miscellaneous weirdness reported by donors

Collaboration

• Continuing work on Echo notification, including cross-wiki and messaging refinements, and a multi-wiki MediaWiki-Vagrant setup to work on this locally.
• Fixed a production issue with a page on English Wikipedia
• We had a problem with Nuke in production that wasn't caught locally, so had to revert release branch. FIx is about to be merged.
• That revealed our local setup needs to be closer to production. I started working on that. Preliminary step was to have MWV stop using root for DB access, which was planned anyway. Later we will have Flow and Echo use a separate DB locally.
