Show your macros!

[AlmaMalma]

When the macros are made using System / User Macros, attach them to your UI using 'Hud Layout' and select Hotbar 7. The vertical one.

Now, still in Hud Layout, move your party list over (either a bit to the right of where it is default, though I moved it all the way to the right and bottom, so it's by my spell bars, it's up to you what you grow comfortable with).

Then, grab Hotbar 7 and move it to the left of your party list.

Now, get a few friends a form a party of 4-8. You can then line up the macros in macrobar 7 to you party list. If party members 4 and 5 are pretty much adjacent to their macros, you're set.
