Currently my thought is the profile of such a user would be that they:
- have not visited the site in a month and posted a answer/comment/question
- have an answer/comment/question on the site
- have been on another SE site in the past day/week/etc
Are there any existing queries that attempt to address the topic of finding dormant users that if engaged are likely to become active users? If not, any suggestions/feedback on my thoughts on how best to find them?
