@Seb: why send a letter to Oz and not the States?
Weexchange is registered in australia primarely, as far as i know. And i guess using an american lawyer will be costlier than an australian one when he gets what amount it is about. At the end i only want information first since i dont believe sueing simply will yield any good result. weexchange and ukyo dont have money to be sued out of them.
There are 2 WeExchange companies. One is ran by Graet in Oz, with Ukyo onboard as well, the other is in Texas, owned only by Ukyo and, I presume, its purpose is mainly for running the servers, since, I presume, Ukyo is re-using some of his previous investments and companies for that very purpose (see the other threads).
There might be some equipment to seize there.
