To turn a video into an emoji, cut 1 to 3 seconds, crop it to a square, scale it to 128 x 128 and save it as a GIF under 128 KB for Slack or 256 KB for Discord. One tested ffmpeg command, a script that finds the frame rate and colors that fit, and a free browser tool that shrinks the GIF for you.

Yes. Slack messages, including DMs, can be requested in a lawsuit or an investigation. Most requests go to the company that owns the workspace, which exports them. Slack itself gives out message content only with a search warrant and tells the company first. Slack's own policy, its disclosure numbers, legal holds, and what deleted messages mean.

Clockify tracks idle time only if you turn on idle detection, and only you see it: after the minutes you set with no mouse or keyboard input, it asks whether to keep or discard that time. Admins can see screenshots and GPS on paid plans, not idle time or the auto tracker.

To mention someone in a Slack incoming webhook, put their member ID in angle brackets: <@U0123ABCD>. A plain @name stays text. @here is <!here>, @channel is <!channel>, and a user group is <!subteam^S0123ABCD>. Where to find the IDs, a lookup-by-email script, and what we measured.

If your Discord status will not change, you are usually clicking the wrong spot: the status list now sits behind the current status line in your profile panel. Other causes are a manual Idle that never ends, an app that missed the update, a custom status timer, and Discord outages. Fixes for desktop, browser and mobile.

Slack has no API to start, join or record a huddle. Apps can read whether a user is in one from huddle_state on the user profile, see which channel from huddle_state_channel_id, and get the user_huddle_changed event when it changes. Code for both, plus audit log events on Enterprise.
