I recently answered a question and found out the next day that it had vanished. I suspect it was migrated, but I don't want to go randomly opening 10 accounts in the hope that I might find my answer.
Feature Request: A cross-site list (maybe a page on stackexchange.com?) that shows all of the logged-in user's posts on all sites, regardless of whether they have an account on that site or not.
Is there a better way to do this that I missed?
