I am happy to announce that I have found a way to present my lecture on Allergic Rhinitis on the web. I searched the internet and I found two sites: SlideShare and authorSTREAM. I have selected the former. The maximum size of the files that can be uploaded is 100MB and 30MB respectively. authorSTREAM has beta on its logo. There may be other sites. I don't know how long these websites have been in existence, but there are some great things on the web!!
I'd like to acknowledge the websites whom I used their photos and slides.
