Is there a way to call a specific group of users in the shortcode, either by user ID or some other identifier? I have 130 members on my site and want to display an image directory of the 40 core users, who all have the same @domain.com email address.
Any ideas?
At the moment it is only possible to hide users which you don't want to show up... The shortcode for that is: [authoravatars hiddenusers=admin]
The easiest way to achieve what you want is probably to put all your core users into a separate role and only display users from that role. You can either use core roles like "Editor" or try creating a new role, for example with the help of the Capability Manager plugin.
If you don't shy some programming then another option would be some custom coding... I can help with that if necessary and would be happy to accept patches to the plugin.
