Thank you for the help. I actually did searched for it and found http://bioinformatics.psb.ugent.be/webtools/Venn/ but seems they don't have a publication record for it that will be cited. That is why I directly ask here, maybe I can get as many sites as possible that have been in publication record so that we can cite the paper when we used it.
In case you didn't try searching first, I've searched for you:
https://www.google.com/search?q=venndiagram+server
Here are some hits (I have no idea if these sites work or not):
http://bioinformatics.psb.ugent.be/webtools/Venn/

you can also use http://bioinformatics.psb.ugent.be/webtools/Venn/ , and then mention the url in stead of publication for that tool ;)
