[ale] more reverse DNS questions

[John Heim]

Hey! Its done.  The guys at the web development company, Yahara Software 
(www.yaharasoftware.com) got the ISP Supranet (www.supranet.com) to fix the 
reverse lookup. So we are in business!

I felt itwas okay to plug Yahara and Supranet after all they've done for us. 
And thanks to everyone on this list too.

I've already added wiki entries on how a blind guy can install Windows 7, 
boot grml, and (kindof) change BIOS settings. Well, with any luck, it will 
attract some interest from other blind sys admins and we will all be able to 
help each other keep our jobs.
