Character Spreadsheet made in Excel and using functions to calculate derived values. Best for people that like to type out their sheets before printing as well as those that don't like a lot of math.
OpenOffice format, calculates darn near everything for you and puts it in a nice character sheet.
All of the real work on this was done by a user named "Trent the Fox" in 2007.
I converted it to OpenOffice 3.2 with minor, unseen, adjustments due to the conversion along with small spelling corrections.
