Thanks for your advice, but with 15 years of Linux/Unix experience, I think I'm very well qualified for most positions. Thank you.

The points you make and the advice you gave me is excellent though. Thanks.

I just haven't programmed with PHP for a long time, but I know how to get work done regardless of the programming language.

Me using Linux for a very long time doesn't also mean that I can't use Windows. It comes down to having a preference for the environment I'm more used to, and that environment is GNU/Linux for me.
