Have you ever seen a post or thread that you want to look at again after a certain amount of time?
There is a Fediverse reminder bot which you can use to remind you about a particular thread after a specified time period (it can be minutes, hours, days, weeks, months or years later).
To use the bot, reply to the post or thread you want reminding about, mentioning the bot's account with the amount of time you want. More info and instructions in the guide:
