@butter, i also do totaly agree with you.
@otto, if in-game u don't understand smt, ask for a clarification. IMO lack of grammar does not make a sentence imposible to understand, nor spelling mistakes (to a certain extent) do. slangs and short forms (like IMO itself, ASAP, CD, NMR, and that lot) are waay more dificult to understand than a phrase with poor grammar.
Also, if u ask for a extra effort for non-native players, you should do an equal or greater effort yourself and offer a easier language to those players, as well as english tuitions, etc, etc
What i see here is a player asking for something out of self-interest. Adn funny thing! as butter pointed out, what he asks for, he himself does not even do it.
