Well, i still think its just a title and, being so, it does is correct. If the antling had a name like Nestcommander Gnadgad (lol...just couldn't hold myself...even tho i know LOC doesn't like the likes of this example) it would be correct being capitalized...but just nest commander is a title...who knows due what...maybe we have a nest commander at every nest just like we could have a nest queen...

IMO if you guys want it capitalized you actually should ask it to be named properly ^^: maybe Nestcommander Hastatus X-XIII (argh...for some reason examples from the forbidden ancient lore are slipping through my fingers today ><)
