Yes, of course! I did that a while ago, already and my desired call sign is "Bohemian" - a small jab at my Virgon roots. I did not yet include it in my profile, however, because both my pilot's qualification exams and the exam for CDF operations are still under review by Admiral Rivera. I thought it inappropriate to use my call sign before I properly passed the exams and thus earned the right to bear it!
Thank you for the welcome, Aeneas! I've been training and learning everything there is to know about BFC, and I might take you up on the offer 'till I'm ready to be an active part of the Raven Air Wing. Nice Spanish, btw!
