Go to the search box in the upper right corner of each forum page and look for posts by August, who uses an obturator and who also sings (still). You can also find her through the User List at the top of each page.
Once you find one of her posts, click on her name to get her profile information (including her e-mail address) or a link to send her a private message. She has been very helpful in the past to people whose circumstances are similar to yours.
This is the best place around for information and support.
