What are writers favourite software?

Personally I found the "Yeah write" software to be very suitable, and is great for organising ideas, characters, plots etc. It also produces very clean HTML code unlike the bloated mess from MSWord.

Another handy tool is a spell checker and thesaurus called wordweb. This is very useful if you are using Wordpad or anything else without a speller/thesaurus

Both of these have free versions to download.

Please let others know if you can recommend some other tools.
