@Danelaw I am very interested in your Roleplay. I have watched the shows regularly and rewatched them several times. I have read the books, ascribing to the notion that the two may contain the same characters but are two very different works of fiction. I enjoy reading military history and have done so for most of my life; everything from Ancient Greece up through today. I also spent 21 years in the military, which gives me an inclination to take on the role of a combatant of some sort. It shouldn't be too difficult to guess which one. I'll send you an PM about it.
Regarding the question of Casual (High) or Advanced it really doesn't matter to me. I will RP in either. The only difference between the two is quantity. I can post one paragraph or twenty. If you want to put it in Casual and set a limit on quantity, then it is Casual. If you put it in Advanced and don't set a limit on quantity, then it is truly advanced. Confidence in ones ability to spell and write grammatically correct also determines where an author prefers to work. I can write well in either.
