How do you apply for a guild/static?

I feel like I’m missing something obvious here. I claimed my character and used the recruitment button to look for groups that suit me. I found a few, I click into their guild page, and there’s lots of information about them. Great. They’re recruiting for my class, great! But there’s no apply button, there’s no “contact us” button, there’s nothing that I can find whatsoever to be able to let them know I’m interested.

I must be blind. There’s no way so many groups forgot to list contact info, and it seems weird to have a recruitment and looking for group features but no application system. Halp?
