To connect a subdomain to your site (xx.yourdomain.com):
1) Log into your control panel in your registrar account (where you originally purchased the domain)
* For example if you want to use site.yourdomain.com, you should add a CNAME where the host is 'site' and the target is ''www.im-router.com'.
3) In your sites editor go to Settings> Domain> Existing Domain, enter the sub-domain (xx.yourdomain.com, no www) and click connect.
4) Let us know so we can complete the process. The system automatically directs to www, so we will manually change it to make sure the sub-domain of your choice is connected.
