How about. . .

A feature that enables a member to add a certain word or phrase and if anyone makes a post with that specific word or phrase, the member receives a notification, or it is moved to a bookmark-eque 'tags' area. Maybe a member-adjustable setting to search posts made by staff, members or everyone?

And on the subject of tags, perhaps member tagging in threads, where you can tag a member in a certain thread. so that they'll be notified when the thread is posted in, and said member can remove their tag if they don't wish to be notified about the thread. Maybe something that can be disabled in board settings to prevent impatient members from tagging admins to pester them if their application isn't accepted within an hour of it being posted.

Hopefully I didn't just miss these features if they are already in the version five.

Hi

Our notifications feature allows you to tag a user in your posts. You just type @username and their name will show up and they will receive a notification (unless they disable the notifications).

Sweet, I must have missed that one. But what about the word/phrase tag?

We have a label system on v5 where you can place labels onto topics (and decide who can see them), but these are not related to notifications.
