A short while back, Boldie did a friendly tagging system that I thought worked very, very well.
In short, specific roles in fleet were tagged as
AAA - A
HHH - H
I propose to make this a standard practice as it's damn useful for all concerned.
For FC's and logi to see on screen where they need to particularly watch. For dps/snipers to see at a glance where their anchors are and especially for drone bunnies to help keep one eye out to ensure they are not chasing targets out too far.
As a fleet aid it is easy to implement and so damn easy to follow but most importantly, very effective.
