1) Allow Mods to put people on "probation". This means prohibiting posting privileges for a limited time due to dickishness/rule breaking. It bets the trichotomy of warning users, locking threads and banning users. The Something Awful fora have success doing this.

2) Allow posters to apply "tags" to threads in addition to posting it in the correct forum. For instance, I may post in FR-NL and provide the following tags: OOP, OESD, deepstack, 50NL. Searching tags is better than just searching text alone. dailykos.com does this with success.
