I have used Lotus Notes for storing campaign material, but this is a rather large expensive package (though our nice organisation has organised home use liscences for employees). It is also a bit of work to design databases (though there are templates for journals etc). I made forms for races, religions, cultures, rules, player queries and also a character sheet (this was for 2e). I have given p on using Notes, just too cumbersome, so I am intrigued by OneNote.
There are freeware and open source notetaking products:, eg:
BasKet Note Pads
Jarnal
Springnote
Tomboy
WikidPad
Xournal
(hee hee and Keynote, I now see having got round to saving my post and see the above message... I will check that out, thanks)
Anyone used any of these?
