So you have an ArcGIS account and you'd like to collaborate with others. It's so easy, just invite or be invited to join a group....ahh but wait. In order for your profile to be discoverable by other ArcGIS Online users, your profile needs to be made public. A public profile allows other users to invite you to participate in their public or private (Org. Acct only) groups. Follow these steps to change your profile settings.
Change your profile settings:
- Login in to your account, public or organization
- Once logged in, click your login name and select My Profile
- Click Edit My Profile
- Be sure to select Everyone from the options for Who can see your profile.
Special note for users with an ArcGIS for Organizations account.
Be sure that your Role has privileges enabled to join external groups. This permission is controlled by your Organization administrator.
