I propose the implementation of a reminder feature on math.SE, which can remind users to take certain actions on the site after a specified time period. Under each post, there can be a "Remind" button. On clicking it, a user can have $2$ dropdown menus, something like:
$$\text{Remind me to} \; \boxed{\color{grey}{-\text{Select}-}} \; \text{after} \; \boxed{\color{grey}{-\text{Select}-}}.$$
The following are some use cases for the feature:
- Remind me to answer
- Remind me to comment
People may be in a rush and be unable to answer or comment at a specific moment. They may also want to conduct further research which can take time. A bookmark is valuable, but a reminder is more explicit (you won't receive an inbox notification with bookmarks). Moreover, a bookmark is generic, whereas a reminder will remind you of exactly what you need to do.
- Remind me to close
- Remind me to delete
Sometimes when new users post questions, they may not be up to site standards; however, they can improve the post with suggestions from other users. This can take a while. Closing immediately can be problematic as reopening takes time and can also drive new users away. A reminder can help an experienced user come back to review a question after a period of time and then decide an appropriate action (closing, deleting, etc.).
- Remind me to bounty
Since once has to wait $2$ days to bounty a question, it can be inconvenient to have to consistently track the time left. A reminder to bounty can hence help.
- Remind me to [special action]
This can be a personalised note that the user leaves for themselves to review after a certain period.
There are probably many more actions that I have missed that could be implemented (Remind me to flag, share, cite...) to ease activity on the site. Perhaps more functionality can also be added, such as reminding on a specific day or choosing the type of reminder (email, notification, etc.). I'd love to hear suggestions and feedback on the feature.
