G'Day.

Have been familiarizing myself with WP Multisite and Domain Mapping.
Now have a good understanding of WP Multisite but have been unable to get Domain Mapping to work.
I have a WP Multisite at http:aussiesportsman.com and want to Domain Mapping http://ouraussiesportsblog.com to http://aussiesportsman.com/icehockey (which is one of the multisite sites).
I have set up the Domain Mapping and A Record but it has now been some five days and it still won't map across and al I get is the popup message saying it takes from 15mins to 72hrs. Well it's now been over 120 hrs.
I've attached appropriate screen shots.
Any help would be appreciated.
Cheers,
Michael.
