I don't think scratch directly does updates to the forums, I'm pretty sure that's done by DjangoBB, and I heard that they were no longer doing updates, which is part of the reason we don't have 3.0 scratchblocks. Support, it would make linking to users much easier. (Does the ST even update the forms now? I don't know.)
If it were viable though, I'd love to see this!
don't hold me to this i saw it earlier today but idk how old the post was
