I saw Mobysaurus here and downloaded it. Saw it was a good thesaurus, but what really got me was the support for WordWeb Pro (and the free too I suppose). Rough Draft, a free word processor for writers (does not have the excessive bells and whistles that Word has; it has just the necessary for writers.) uses WordWeb Pro as its dictionary and Mobysaurus does too. The three, Rough Draft, WordWeb Pro, and Mobysaurus are the most important elements in my office. I own a license for OfficeXP, bought before I knew better. and the OpenOffice suite though free suffers the same malady as Microsoft Office. I put together my own office 'suite' of just the components that I really need.
Thank you for Mobysaurus.
