I’ve just uploaded two presentations documents onto http://www.docstoc.com for download. (Do a search on my name). It’s the first time I’ve tried using docstoc, so it’s a bit of an experiment. Ones about things you daren’t get wrong in your presentations and one is a bit more chatty – my top ten tips on a wet Monday afternoon! :)
Some of the stuff I’ve seen there has been great (and some of it hasn’t!) but if you’re looking for default templates and so on you could do worse than look at some of the ones available there. A note of caution though – some of them are shockingly bad and you shouldn’t assume that just because it’s there, it’s useful!
(A bit like life and this blog, really!)
