contributed more than 11 million articles in 265 languages.More than 275 million people come to our website every month to access information，free of charge and free of advertising.

But Wikipedia is more than a website.We share a common cause：Imagine a world in which every single person on the planet is given free access to the sum of all human knowledge.That's our commitment.

Your donation helps us in several ways.Most importantly，you will help us cover the increasing cost of managing global traffic to one of the most popular websites on the Internet.Funds also help us improve the software that runs Wikipedia-making it easier to search，easier to read，and easier to write for.We are committed to increasing the free knowledge movement worldwide，by taking on new volunteers，and building strategic partnerships with institutions of culture and learning.

Wikipedia is different.It's the largest encyclopedia (百科全书) in history，written by volunteers.Like a national park or a school，we don't believe advertising should have a place in Wikipedia.We want to keep it free and strong，but we need the support of thousands of people like you.

Thank you，

Jimmy Wales
