Coder, I have thought about those, however sending text (SMS) has a cost attached to it that I rather not get involved with. I have thought about Whatsapp but not everyone uses it, checks it and since the API / FB connection I rather not use it.
Thomaslee, this Thread is not about how Members stay in touch with each other. This is about how site owners stay in touch with members outside of Email.
Rather off topic, but...
Rules on that will not change. People can continue to use FB / Other sites for that sort of exchange.. Spammers, trolls and leechers will take full advantage as has been our experience.
