Pinned help channel digest message

[Josh-Cena]

From T6:

In each #help-* channel, have a pinned thread containing a digest of help thread activity

A lot of helpers have noted that they miss getting an unread indicator whenever a question got bumped, and feel that questions are consequently going unanswered.

I propose having a thread in each help channel, managed by the bot, that catalogues all active help threads, like the Active Thread list. Each message would be something like

TypeScript: "geoffrey - class with a constrained recursive type" - 12 messages, 3 helpers joined

Every time a thread is bumped, the bot would delete the previous message for the thread and move it to the bottom, causing the digest thread to be bumped, and making the digest thread sorted by activity.

When a thread is closed, its message is deleted.

This would solve two problems:

• The active thread list is spacious and often requires scrolling -- this would be more compact
• Helpers don't get unread indicators for every thread -- if desired, helpers can join this digest thread, and will get orbs every time a thread is updated.

The active thread list would still, obviously, be available, for those who prefer it; this is to provide helpers with more options.
