and you’ll see a capability for a user to close their own topics.
you need to either amend the participant role, or create a new role with this capability

@robin-w Thank you , Can i easy to changle “subscriber” can be close their’s topics.
you won’t be changing subscriber – that is a wordpress role – bbpress has it’s own roles, and probably that is participant.
I’m sure you can , but haven’t tried so don’t have code offhand.
Suggest you just create a new custom role, and then set your bbpress user to it.
There codes looks complicated. Can u tell me which capabilities is allow user close their’s topics. @_@
