After going back and reviewing the directions, i have to agree with Tim’s comment on my previous post: the Slidy instructions include a lot of detail that isn’t essential to somebody just getting started (though it lets you do many more advanced things).
So i created a quick start template (which is itself a Slidy presentation, of course): you’ll find it at http://www.semanticbible.org/blogos/gems/SlidyQST.html. You should be able to modify this to make your own Slidy presentations with a minimum of head-scratching, provided you can edit basic HTML.
