Yes title says it. Grant permission to BN's to lock their own topic specifically queue. New mappers tend to bump and post on closed BN queues. As QAT members can lock any topic, i think BN's should have permission to lock their own queues at least.
I don't remember being able to lock when I was bn, but then again I didn't actually try to.
It'd be cool if it was possible tho + being able to unlock ofc :3c
Yeah as QAT members can lock and unlock any threads why not give BNs give same permission but only applies to their own threads. That won't cause any harm imo.
