Hi buzz: are you comfortable using "Trigger Zones" & "Setting Triggers"?

I know what they are and i can follow any instruction for doing it.

I hope this will explain it for you.

I'm just across the RIVER if you need more Help.

Thank you very much for your help, it did part of what i am looking for. I will pm you a photo and try to explain better what i am missing.

Except for intercom mode it wouldn’t be realistic. If they were the only one using a secure comm key is the only way I see it in rl. And I doubt they try that for security concerns.

I did get your message but I couldn't attach the Pic.

Let me know if you need more Info.

Thank you very much for your help, it was what i needed, everything look fine now.

Salutation, Claude
