I always like Arren mostly for his personality.. i think he was one of the most honest people I get to know in my life. Since the very first chat I saw he will be direct but funny trouble maker. And indeed, many people found him too direct, sometimes ignorant to the world around.. but in fact it was all him. He knew exactly what he wants, he fight with people when there was no agreement.. but at the same time he would stand like a wall to defend and protect his people and his idea. He gave me impression of strong but also very warm person, who really knows how to built successful team and more then that.. a family. I will miss his sense of humor and honest opinion that we all could always count on. Its a great lose to mpi but also to all community.. Monika Chodasiewicz
