If you moderate an Assistance forum (Mapping Assistance or Modding Assistance), you will notice that if you look in the bar below the standard Moderation options, you can "[Solve] Topic"
This closes the topic and tacks on "[SOLVED] " automatically in one motion.
Note that due to some of the freaking out after the hacking, using the moderation option sends you to a blank page, but still executes the action.
