I just looked at the donation page. It is good. However, I think you may provide more methods to get money for wikimedia. For example, selling T-shirt printed with wikipedia log, similar sticker for volunteers to put on car bumpers.

Sometimes, people are more willing to get something while contributing. And those things I mentioned are useful to spread the effect of wikipedia.

I saw a lot of bumper stickers everyday. And some are very interesting and very impressive while some hurt my feeling a lot such as "Free Tibet". I don't like the idea of fission my country with the excuse of wrong behaviors of government.

I would definitely buy one with WikiMedia slogan and put it on my rear bumper to proudly declare: I am a wikipedian! Joint us! And I would wear the T-shirt often too :-). But make sure you provide size M suitable for asians. Most T-shirts in USA are too large for us.
