The naming won't work, too confusing on the one hand, too ineffective on the other, hands an edge to players who post less, forces those of us who post more to either surrender any advantage or devote lots of effort to masking ourselves, effort better devoted to worming out data, scheming etc.

Anyway, one just names the characters, a few of my prepped games have characters by name to be introduced right from the outset, and in Mad Muad they all had a 'name' ... Arafellian Commander, Lesser Saldaean Noble, Dark Green Ajah etc.

Clues are always a nice addition to games, and descriptions are some of the better ones to use. If you begin with each role having an open description, or even a name, like a personae dramatis at the beginning, you eliminate much of the confusion. There's a whole smear of ways to do this, like simply giving everyone an open identity, A the Baron of Y, B the Earl of X, etc. In a sub case, A the Baron of Y takes ill and his 'nephew' C has taken the duty and title over, etc
