This is the English Amiga Board, so it's good manners to speak English IMHO... so that everyone can understand us.
Besides, I've been doing it since I was 4. Even in the old days, you'd be hard pressed to find a pure portuguese BBS (although portuguese sysops were easy to find
). Almost all of my technical textbooks in university were in English. When I finished my degree, there were a couple of books coming out in their Portugueese/Brazilian guises, but translations were confusing, unfamiliar, and sometimes downright hilarious! In the Sedra-Smith tome, for example, edge-triggered circuits translated to "circuitos engatilhados pela borda"!
