Well, there's Harvens Custom Map Pins, but I don't believe they show up in the compass to track, like the blue diamond does. If you are looking to have multiples of the marker like that diamond one, I don't know of an addon that does that, and I'm actually not sure if it's even possible.
If you're talking about pins just for you, Harven's works fine.
If you're talking about group-visible pins/rally points, you're limited to what the game provides: Ctrl+click for each group member and Shift+click for leader.
If you think anything I or somebody else said violates the Rules of this Forum, you are free to flag my posts. Till I get any notifcaion from this, I just asume you know you have no case against me or Zenimax disagrees with you.
