As you already know, to purchase something on your Getsocio site, people should have a registered account. To become a user they need to create an account by filling out the Sign Up form or use Facebook Login for instant account creation via Facebook (if you have set up the Facebook application). After they set up an account, they will be able to login through Sign in page.
When the person is logged in to your site, he/she can fully navigate through the site and use all the features of it. Logged users have their own "user section" where they can control the account – drop-down menu with My Info, My Purchases and My Gifts options:
Note: The above menu is accessible to holders of all registered accounts no matter what the user role is. This means that all users on the site can access drop-down user menu by going mouse over the Hello, user_full_name wording in the top right corner of the site. Besides being able to purchase deals and managing own account, registered user can also leave comments on the deals (if you have Comments option available on your deals).
On your Getsocio site you have a number of settings that let you have a full control over the user registration process:
Site admin can view the list of all registered users under Users page of Admin section. There you can also download CSV file with information on users.
If at some point you decide to restrict access for some user account (the reason for this can be, for example, inappropriate behavior), you can just disable a certain user. Go to Users page in Admin section, choose the needed user and then toggle Enabled next to user's full name. Once you have done this, the user will no longer be able to login to your site.
All users on the site are registered through Sign up page. So if you want to create another user account for testing purposes, you would need to log out (or use different web browser where you are not logged in), go to Sign up page and submit registration form. After this you will be able to login to your site with the needed account.
When new users are registered on the site, their default user role is regular User (or customer). But you may need to change the user role and give certain access to Admin section for this person: this can be Vendor, Staff, etc. To change the role, you should go to Users page in Admin section, click the preferred user and choose the role in the drop-down on the top-right. The role depends on your preferences.
