While it seems you have all the good intentions, i must ask are you a member of the sca or do you play with us?
As an officer in my barony and licensed fighter in my kingdom, i feel its nessessary to say that all are welcome, yes it is difficult for the fringies on the outskirts to get into the core of what the sca is since many of them find it daunting to move into such a ordered and cerimonial group.
Yes, there are those who will rudly show dishonor by looking down on those new ones instead of helping them. but most of us remember what it was like to start out, it takes time and a lot of effort to really get into the sca, but many newcomers start as generic vikings (easy stuff) or Pirates, yes the argh matey and slurring kind, and that is fine with most of us (the ones who count), there's nothing wrong with being a pirate.
Yes it does fall outside the barrier of the prime sca standard but we are accepted anyway...oh did i mention i'm a pirate? i carry a .50 flintlock and saunter around the erik, i am also a viking and follow all my needs there, just depends on how i'm feeling to how i dress. there are no set rules of how to's, as long as you obey the laws (mundane and society) and keep your courtesy held high, showing those their due respect, then all should be fine, and you'll be accepted by those who matter.
I am also a merchant and those bloody pirates bring me more loot than others combined.
oh yea, just because people are "concidered" to be landed nobles does not mean they have to use it, you may be a pirate, a thief, or a beggar, i will still call you Mi'lord. its courtesy, its polite, its the Society for Creative Anachronism, the S.C.A.
