I think Sadfar is offering to help sort out on an open source piping software project.
Put on the conical hat with the big D on it immediately, and go to the corner of the room.
Cheers
Steve McKenzie

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