Bespoke sub-domains are available to all Huddle customers. This allows you to first brand your URL then set your logo on your login page and within your Huddle account.
To get this set up first consider what you want. Huddle's default sub-domain is:-
https://my.huddle.net
You can change the 'my' to whatever you want i.e. https://MYCOMPANY.huddle.net
Once you have decided you will need to email your chosen sub-domain to help@huddle.com
