No. JSngry & I can both approve their posts. But if I don't turn this option on, they would be free to spam us if we're away from the board.
My intention was to turn off post approval if the person is legit. I know of no other way to approve these people without risking this place becoming Spamville.
That being said, I am open to suggestions. I doubt "approve them all" will work as there are almost 11,000 accounts awaiting approval dating back to 2016, which is when Jim A turned off auto-approve.
