A small follow-up from myself with player-related commands...
* The /buddy command (or the default key b) will open the buddy list. Add players that for some reason are important to you, and you will be notified when they enter or leave the game. Once a name is on the list, you can use the Edit function to add a comment to the name.
* If a player annoys you, you can use the /ignore command - The Sound of Silence (from that player).
* If you really feel offended by somebody, you can also use /report PLAYER_NAME. This will log both the previous and coming five minutes of the player's actions.
With some luck you will never need the last two commands, but it is good to know them, just in case.
I still hope more people will share tips and tricks. I know that some of you out there use a lot of macros, for example. Why not share them, and help everybody a bit?
