As you may or may not know, there is a Discord bot called FRIDAY, replacing GINABot in a positive manner with actually working and some extra features (such as Hive-Engine support) available.
You can find the announcement here if you have missed it before.
Unfortunately, some features such as witness notifications were broken for a while (or did not work as initially intended) those are now resolved and added.
So all witnesses are able to use missed block and price feed notifications from now on. If you are actively monitoring a witness you will have access to extra features regarding witness settings on the settings page.
You can enable and disable notifications such as price feed notifications (when a witness hasn't published a new price feed in the last 24 hours or they updated their price feed) as well as block notifications (a witness has missed a block they were supposed to sign) on FRIDAY.
In the upcoming days/weeks, I'll try to add new features to FRIDAY such as notifications for governance vote expiration, savings transfers, account key changes (for account protection) as well as signing key/backup witness notification for witnesses.
If you have any questions or feature requests, please feel free to let me know.
