The assumption here is that you have my phone number. If you don’t have my phone number, and you think that’s an oversight on my part, please send me an e-mail at email@example.com and ask for it. If you don’t have my phone number because I don’t know you, I am usually pretty responsive on e-mail.
In order of preference:
- FB Messenger: you can use it without a Facebook account.
- Google Hangouts
- SMS Message
