I only know about the /slap command, since you made it a point not to mention any others... also being able to customize the slap would be sweet.
Like the rest of you, I'd really like to know what the other commands are. Also, I wish that the /slap command would generate a random thing to slap people with each time, instead of only slapping people with trout. The customization idea is cool too. Either way, the creator needs to tell us more about the script and the commands in it.
