You guys should do like.. if others have this app, that they can send it to those who do like if it's just a messaging app like WhatsApp or Telegram type things. And the marked red could be the accent color. I would love that so much. And if they don't, regular SMS and to sign up could be with your phone number or something. But they would have to have Textra to message with data or wifi and have the option to opt out of it. And maybe these people would have read receipts with the check marks like WhatsApp but have the "last seen at" from Telegram. I would love it. Hopefully that happens!
