I have been sent some further spells and a character class by Ben Sutherland today, these have now been added to the data file. There are also some other minor alterations (and with D&D Manager 2.2 or later you can overwrite existing data correctly). This can now be downloaded from the data page (direct link here).
Thanks for all the contributions so far from Patti Devlin, Go Endo, Eric Rahm, Ben Sutherland and Wordman. If you have any further contributions, please send them to me so they can be included.
