Owning a car is one thing, signing up to the owner/enthusiast club is another. For most people it indicates an active interest in the subject, and a willingness to participate, even if it's only "yea that happens to me too". that can be helpful too.

If people help you, then it's good manners, to be as helpful back. I ain't a developer or a coder (poor vbscript isn't much use around here), but I try to contribute where it is positive, even if it is just saying thanks.
