I had to check to see what you are talking about blueee and see that it was in Chains. The rules for the particular chain is normally given in the first post of the chain (not sure about continuation chains, but Gatsby will explain them to you if you ask him). No one intended to upset you, they just told you the rule of the chain that you were playing in - I am sure you wouldn't have wanted to mess up the chain and not be told, frustrating the other players.
We also try to avoid chatspeak and 'non-words (such as diss) in these forums as English is not the first language of some people and also the age range is great, 'diss' means nothing to people of my generation, I am assuming it is meant to mean disrespect. It could confuse non-Engish speakers too as it is not in the dictionary so they cannot look it up to find out what it means. We also try to use proper capitalisation as that makes posts so much easier to read for everyone.
