As a user, I'd like to be able to remind myself of a task, after a configurable period of time.
E.g. `Is it possible to create timed notification? I.e. if somebody reviews GA nomination and puts article on holds for 7 days. It would be useful to have timed notification as some kind of reminder for both nominator and reviewer. --Antidiskriminator (talk) 11:35, 8 January 2015 (UTC)` ([via](https://en.wikipedia.org/w/index.php?title=Wikipedia_talk:Notifications&oldid=645390435#Timed_notifications))
E.g.2. `[...] With WP:Flow, it might even be possible to get automatic follow-up reminders to reduce hassle for the admins. The main complaint in the past is that admins can't track these warned accounts efficiently, so "one week's fair warning, during which you need to get your name changed" turns into "indefinite freedom, because I can't remember who I warned". But if a Flow process automagically told you when the time was up, then you wouldn't have to remember anything.[...] WhatamIdoing (talk) 19:27, 6 January 2014 (UTC)` ([via](https://en.wikipedia.org/wiki/Wikipedia:Village_pump_%28technical%29/Archive_122#Proposal_:_creating_an_automatic_alert_for_invalid_usernames_upon_new_account_creation.3F))
