Initial simple way to Webfinger enable your domain -- needs PHP.
================================================================
Step 1
======
First, put the folders 'xrd' and 'dot-well-known' on your website, so
they load at:
http://yourname.com/xrd/
and
http://yourname.com/.well-known/
(Remember the . at the beginning of this one)
Step 2
======
Next, edit xrd/index.php and enter a secret in this line:
$s = "";
This can be anything you like...
$s = "johnny-five";
or
$s = "12345";
It really doesn't matter too much.
Step 3
======
For each user on your site, and this might only be you...
Make a copy of the example@example.com.xml file so that it's called...
yoursecretusername@domain.com.xml
So, if your secret is 'johnny5' and your name is ben and your
domain is titanictoycorp.biz, your file should be called
johnny5ben@titanictoycorp.biz.xml
Finally, edit the file to point at your account on your social
site. If you are the only user, then you probably don't need to worry
about user/1 as this will be you. For multi user sites, the user ID is
on the profile page.
Finally
=======
Using this method, though fiddly, you can now be @user@domain without
the need for any prefixes for subdomains, etc.
