(Wondering what does anyone-can-contribute mean? How about a look at Wikipedia FAQ and learn how does one edit a page.)
Anyway, hello, whoever you are--you who have put up AmbientCalculiOnline--I just wanted to welcome you to Wikipedia. I hope you'll stick around and write some mathematics articles for our collaborative encyclopedia. --Larry Sanger
Sorry for the page name. I am not familiar with the free link feature. I have been using TWiki a lot.
I am putting up this page for I am lazy -- I don't want to maintain a resourse page all by myself. So I choose wikipedia and hope other researchers in this field can come here and contribute (at least put the link of their own work here), after I announce the URL. Do you think this is a good idea? Could you find me a better page name? Thank you. --Xudong Guan (this page exists, i believe)
