In case it had escaped your notice, I am a bit of a writer. I know that because my name is on the booklist at WhereTheMapEnds, which you should of course look at as a detailed guide to Christian Spec Fic, but is not the main point of this post.
As a writer, I have spent many a happy hour fiddling with the various world building, character creating and story generating gizmos collected on the site. Actually, these are probably more useful to a bored non-writer wasting a few online minutes at work, than to a writer like myself, prone to procrastination, a cure for which is about the only thing absent from Jeff's Tools for Writers section.
If you haven't already, go and have a play. On your way, you might like to take in the following stops on the tour:
Grace Bridges reviews on of Jeff's own works;
