Go to the adoption page, but don't click immediately on add new request. I guess you've been doing that. You need to enter the name of the wiki and then click on that button. Just fill in the adoption form and you're ready. Also include a link to a blog post or forum post on that wiki you're adopting about you adopting it since there are several people around :)
