Great idea!

A question about the link to Diecom. It is labeled as a .doc so my 
browser insists that a word processor be used to open it. Examination of 
the link contents indicates it probably is an MS Word document.

Could you convert this to HTML or text so it could be read in a browser? 
Could you have both, so the document (converted to text) could be read 
in a browser but also downloaded?
