Pro tip: Prefixing your Lightning Address with a "⚡" helps to differentiate it from being an e-mail address. e.g.,
⚡Cointastical@Stacker.News
This was a convention used by Alby for their browser extension to be able to grab the Lightning address from somoene's Twitter profile, description in a Youtube video, Reddit profile, etc.
Cointastical@Stacker.News
