If your presentation is under a free license, it would be nice if you could upload it to Wikimedia Commons, preferably as a PDF file.
OK what category do you want us to use?
I am not an expert on Commons by any means, but I think we used [[Category:Wikimania 2009 presentations]] last year, so something along those lines I guess.
