The current naming limitations just seem... archaic. Sure, it won't make a difference in game performance, but increasing the character limit and available characters would allow people to use clearer, more adult, easier to comprehend callsigns. For example, changing the limitation to 12 or 16 characters and allowing dashes and underscores would allow someone who enjoys hunting ducks to use the callsign "Duck_Sacker," whereas they were previously limited to using "DckSckr" (which resulted in many unwarranted, colorful PM's from in-game players).
Is there any reasoning as to the severely-limited naming conventions? Would it be easy to get this to change? It just seems like a really small fix that would make a relatively bigger difference and allow for some more creative (and original) callsigns. Allowing dashes and underscores would be a big improvement, instead of requiring everything to be run together.
