We want to reduce the abandonment rate of our Wikibases (empty+deleted total to 50% of our user base), and understand why this is happening, and thus want to monitor:

Weekly report to Wikibase Cloud team (To find if there are any patterns and see if we should reach out to anyone):

• Average time to engage (Wiki created -> First action (action=any data created))
• When do people abandon their Wikibase? Abandon=more than 90 days inactivity. What was the average activity before that? E.g. I created a Wiki, played with it for 1 week, then abandoned it. 90 days later we observe my abandonment of my Wiki. We register the abandon time = 1 week.
• Average number of active editors per Wiki-> As to understand how community oriented these are and if it's individuals managing/testing things. Active editor=performed an action in the last 30 days)
