Thanks for the replies!
Dorth, I think I know which programme you are on about, called 'Knight Club', or something like that. And yeh looks like some expletives really goes down at those international tournaments.
Bofur thanks for the insight, I think the group I'm look at (the Northumbria Vikings (part of Vikings-Online) but does all of the early medieval period) is mainly the 'Living History' aspect, but you're right I don't think I'll want to jump into anything too extreme at the moment.
Just something I've always wanted to do so I thought, why not?
