@Butrflynet,
Good work, BFN.
We get a lot (well, it seems like a lot) of these questions and an individual may answer kindly once or twice, but since these questions are a common assignment, the individual may become weary. Some posters even argue back that the person who answered is not positioned right in the industry, in an annoyed tone.
To ionus, usually people aren't so traceable, or others wouldn't likely be interested anyway, but I'll admit you have a privacy point.
