On each page is a contact form. You can send the authors name there and we will add them as soon as we can. Depending on the size of the author, the turnaround time can take from a few hours to 7 days.
If you search for an author and they aren't listed, a page will appear notifying you of this. There will also be a contact form, with the name you searched for already automatically filled in so you can simply click "Send".
