As the name suggests, collaborative threads would be a wonderful accommodation. The ability to add other players as thread admins (that can actively edit the thread) is something I believe would be helpful to many. Like clan admins, threads should have the option to list IDs that are able to edit the thread. The reason I suggest this is because some threads are monitored by multiple people, especially suggestion threads, auction/sale threads, and guides. The ability for the thread owner to manually add editors would be a HUGE help, especially if the managing account(s) are inactive. That way, trusted users would still be able to contribute to said threads.
