Private Threads
 

Kentaurus's hack here isn't supported anymore, nor does it provide all the functionality we needs, so I'm hoping someone might be able to help us with this.

We need the ability for certain specified users (Not usergroups however) to be able to post things only able to be seen by certain hardcoded usergroups (ie. The mod/admin staff), themselves, and users the poster specifies. The ability should be able to be turned on or off both for usergroups and individuals, and would need to be able to be disabled in specific forums. Also, it should be possible for that person, or a mod/admin to change the privacy settings of the thread, either adding/removing allowed users, or making the thread totally public. Likewise, it should be possible to make a currently public thread private.

Anyone up to the challenge?
