How can a user contribute to the bitcoin.it Wiki?

If a user wants to edit a page on the wiki or contribute to it, how can this be done? I have been searching all over their site but I'm haven't found the answer.

I did more searching and found a link on reddit that lead me here:
https://en.bitcoin.it/wiki/BitcoinPayment and https://en.bitcoin.it/wiki/Special:BitcoinPayment

I should have just searched the forum because I see it's been asked before. Also another question I had was how long will it take to be able to contribute, and the 2nd page says "Please note that you will need to wait for your transfer to be confirmed"
