Today we’ll discuss setting up your Dolphin Pro website so only people invited by you, or your members, can join.
Start by logging into the administration section and clicking “Advanced Settings” under the “Settings” tab on the left column menu.
Next click “Profiles” from the list of choices in the center of the screen.
Now place a check mark beside “Enable Registration By Invitation Only”.
That’s it, your site now only allows joining by invitation only. This is good if your site is of a private nature or you just want to eliminate “spammers” from signing up.
