That thread didn't inform anyone of jobs in Portugal. It just informed two users (that didn't bother sharing their information with others, and that's what Fora are for) that they got mail. That's private use of a public Forum in our book. If you want to discuss jobs in Portugal, start a thread that actually talks about jobs in Portugal.
To answer your question, the right to decide about the Forum management comes with the appointment to Moderator, which I received from the Board Administrator six years ago, and who, BTW, gave me the tools to close/open threads between other moderating powers.
jettesen, you seem a nice enough chap, but I have the impression that sometimes you tend to act a little hastily without having the time to switch on your logic skills (the ones Eddy gets to master even in a 5 words sentence). They do help a lot in life, you know.
