Thanks Hans,

I'm just flying by the seat of my pants.  I will try your suggestion.  I need compensation tables from the DEF 14A.  I spoke to a SEC representative yesterday, and she told me that DEF 14A is not yet available in XBRL format.  I like your download-to-notebook-format idea.

Thanks once again,

Gregory
