I have just came to his server as well because i was conviced to do so by some of my friends. This far I can say there is a lot of work to do but the server looks realy promising.
As you noticed i gues this is a BR server and most of the players speak only portuguese. So here some usefull link to web translators what makes your communication a little bit more easy.
and here are some shortenings in portuguese
sim prb=no prob
amo= i <3...
eu não falo o português= I do not speak portugues
When you talk with people try to pay attention to not use shortenings and allways be polite. Remeber we are the minority here
