Hi Paul,
Just wanna know what do you think a software tster is? Nowadays Engineers are woking as software testers for engineering software. I am a civil engineer and working as software tester in a company that develops CAD related software.
I just wonder why a software company should invest time and revenue in open source software? What benefit could be reaped from such an investment? Anybody can customize the software and its available for free in the market? By the way my name is Safdar not Sadfar :-)

Is it just me, or is it very amusing to see a software tester offer to
help
out Steve with engineering?
