1) Allow journal owners to "unbump" threads in a fashion similar to how necroposted threads in regular forums can be. (If this is already possible, make it somewhat more obvious.) [from me]
2) Separate the "Protected" setting into whitelist and blacklist modes. [from Kirby, over Skype, because he's too lazy to make his own thread about it and insists that a thread that was originally going to only make the first request should have this one as "related" even though necroposting and spamming have little or no connection]
