+bbtimeout
From Elendor
Syntax: +BBTIMEOUT <name>=<seconds> **Admin-only** Bulletin board messages are automatically purged from the board after a suitable delay. This delay defaults to 1 week but is customizable. This command allows setting the delay period to any integer number of seconds. (Note that the purging will not be exact. Purges of bulletin boards occur three times a day.) Example: +bbtimeout public=86400 (This would cause messages on the public board to be purged after one day.)
