I know you're a PIMO, so am I...

Since waking up, have you found a reliable way to identify and speak to other PIMOs in your hall or area, without outing yourself?

Obviously a codework or sign etc wouldn't work because elders or other JW lurkers here could learn these.

There must be a logical way to do it. Any coders here? Two computers can talk securely to each other, and whatsapp is end to end encrypted. Is there a principal that can be applied to two PIMOs becoming aware of each other? Like a PIMOdem 😁
