Hi, Linguistics is a TRAINED skill and in the forgery rules it states that: Your Linguistics check is opposed
by the Linguistics check of the person who examines the
document to check its authenticity. What im getting from this is that only someone trained in linguistics can detect a forgery, I think this should be changed, I think that if you know the handwriting of someone you could recognice if someone tries to forge a letter using his name, at least you should be able to try, if the forgery is good you fail because is an untrained skill but if it not that good you could be able to identify it as someone elses handwriting even if you dont know how to forge a signature or letter.
Well thats my two cents so far.
P.S. Sorry for the bad english :P
