Too much time trying to figure them out, rather than getting on with content. But I don't intend that as a criticism, just an aside:
- yWriter5 is freeware from SpaceJock Software
- The Snowflake Method from Randy Ingermanson might interest you - his Snowflake Pro software will cost you $100, though.
Indeed, if you like early-uptake, and don't mind beta-testing (i.e. finding bugs and not complaining about them to the manufacturer - just reporting them as feedback) then you can already download it and get going. Beta Test Download here
As software goes, it has always seemed really cheap (£30-40) and (even better) if you 'won' on NaNoWriMo this year you get a 50% off coupon, too!
