I keep my secrets close to myself in case I need that job one day!
I found pprune no help for getting a job, the only thing it really did for me is put it into perspective of what the industry is like.
I don't help people get jobs at all with my posts in this section. My posts are more of a "there are jobs out there" and "it's not as bad as they say" as opposed to "here's a job you should apply to". Not to say my posts aren't helpful...most of the time.
I did find a good few things though when I was looking for a job, none of them came through but they were good leads I hadn't heard anywhere else.
