Highlander, if your e-mail didn't go through, they won't be able to find it even if they search. Tibby looked for mine in her inbox, and in the CPC inbox, and it was not there. And the bad thing was, I got no notification that my e-mail hadn't been delivered, so I had no way to know it didn't make it through.
I hope Larry has now been alerted, and the NTM e-mail system will get checked and hopefully modified. I understand they may be wary of getting e-mails from strangers, but truly, if important e-mails regarding MK abuse are getting lost in transit, they need to be concerned.
For now, I suggest you request a confirmation from the recipient that your e-mail was received. And if you don't hear back, maybe re-send it through a New Triber you trust?
A last resort -- gasp! -- would be to go back to snail mail, but that is almost against my religion these days!
