I get the hesitation, especially since a half-hearted channel can feel like another job. One low-effort option is to repurpose clips you already have into short, faceless teasers that answer one question each and point people back to the forum. If you need to save source clips from TikTok for those teasers, something like TikTokio cloud can help, but I'd keep the focus on being useful rather than posting just to fill a calendar.
