Thanks jaimehlers for the translation. Makes it much more understandable.
Ok found out that using Google translate breaks the link buttons so I threw together this tutorial...Hope it's helpful.
The text within the red circle is your registration form.
Here's the text from that box translated for you to refer to. Make sure to fill in everything. If you don't select your Gender or fill in all of the info by birthday it will return an error.
With that completed you should see something like this. Fill in the text thats within the picture and click on the orange button.
You should receive an email that looks like this. Click on the Mail authentication link I circled.
After verifying your email go back to
http://www.pixiv.net . This is an image of their translated website. Click on "Settings" or the original Japanese text which will be in it's place if you are on a untranslated version of the page.
Scroll down in the Settings page until you see these selectable buttons.
This is the translated version of the settings with the buttons selected to show all pictures and what your settings should look like.
Now scroll down and click this button. You should now have full access to view all pictures on that site.
Hope this was helpful. Information accurate as of 7/28/2010.
Attached is this information in BBCode within a txt file. If the need for a tutorial pops up again simply open that, copy and paste it into a forum reply and you should be good to go.
Edit: Also if you're incredibly lazy here I just attached the 'continuation' images here. Pretty sure the one in the mirror is the only continuation but I'm not certain. The other image isn't too bad either really.
