Electronic is always the best form of communication. That way I can choose to ignore things when I want.
You can try to text me at +1 (808) 825-4636. If that doesn’t seem to work you can try to text at +1 (305) 767-3144. A text should reach me at these numbers no matter where I am in the world.
If you want to have a voice number let me know that in your text message or ask me to call you at the number you provide. If none of these work there is always email at firstname.lastname@example.org or Facebook Messenger if connected. If you have tried all of these and have not heard back in at least 2 weeks then maybe that is by design -sorry.
