Any other methods of contacting a member?

Mega lurker here, but I’m attempting to contact another member here (“AFshirt”) for something they have in the Equipment Exchange. I’ve sent a PM and an email, but as I’ve not heard back I’m wondering if they don’t get PM notifications/emails and/or emails originating from M4C are going to their spam folder. They haven’t logged on since March 14th so I may be grasping at straws in the dark anyway, but figured I’d check. Thanks in advance for any help anyone may be able to offer!
