I disagree, Fingal. When you reach guru status, you'll have learned something new. I've frequently learned new stuff just by trying to answer other users questions. I've sometimes had to look stuff up, or read up on something that I thought I knew and ended up knowing it better. It's all about the journey, after all.
In my opinion, you don't even get to be 'Linux Engineer' on here unless you've learned more than you knew at 'newbie', you just cant post enough questions to do do it, you
have to answer questions to get your post count that high. And being a guru isn't about knowing all about Linux; it's really about knowing where to look for the right answers
And Hazel, if you're still paying for local calls, then you should consider changing your phone provider.
