Is it possible to show the "date joined" on a member's profile?

Hi Flip. Currently, these are the options:

1. Admins and Moderators can see when was the last time a user logged in to the community: On the profile page and from the admin panel too
2. Admins can see when was the date that a user joined the community: Admin Panel> Members

Showing the account creation date to all members probably won't be ideal for all use-cases, but for sure there are use-cases like yours that can help. I am adding the "feature request" tag to this post to bring it to our product team's attention.
