Another ancient thread resurrected from the depths of somewhere?

Anyway, in response to some questions, first decide what programme you're going to use to write with. I wouldn't try without a dedicated word processing prog. Then, although auto spell checking can, at times be a nuisance it can be handy if your spelling's not too hot. You can have a grammar checker too (but I turn mine off). With spelling, if you deliberately use a word which isn't in the spell-check dictionary, you need to be able to "add to dictionary". It's handy if your WP prog also shows you when you've accidentally got an extra space.

When you've written your work, you need to proof-read properly to look out for errors and plot-holes and if your work's long, regularly save to a flash drive.
