Domain management
When you open a Wild Apricot account, your initial Wild Apricot website address is provided for free within one of our own domains. It is generated automatically based on the organization name you have entered when you opened a trial account, but you can change it at any time. You might already have your own domain and if you have a billable Wild Apricot account (but not a free one), you can set it up to use with Wild Apricot. For example, instead of using a free Wild Apricot address like nycs.memberlodge.org you can buy a domain nycs.net and have your Wild Apricot website at www.nycs.net.
Domain management page is where you control these settings.
The first time you get to this page it will have only one record - your initial free domain:

You can freely edit the first part of this free website address and select one of our subdomains by clicking on Change link:

To add your custom domain (which you already own), click on [Add custom domain] button:

By default, if you add a domain like abc.org, we will automatically add both www.abc.org and abc.rog, because normally you would want people to be able to access your website either way. If you do not want this, delete one of these domains via Remove link.
It is not enough to add it on this page, for your domain to work you have to make the appropriate changes via your domain registrar - See Custom domain setup
You can have many domains setup for your website at the same time - one free domain is always provided by Wild Apricot and any number of custom domains you have purchased. One of these domains has to be assigned as the primary one - it is used in all email notifications etc. You can change your primary domain by clicking on the 'Set as primary' link for a particular domain:
