Questions & Answers

Yes! Simply post them to ElixirStatus and you can be sure that they land on my radar.

Yes. I'd like to consider myself a trustworthy individual, but then who doesn't?

I am, however, an active member of the open-source Elixir community and the maintainer of Credo and ElixirStatus. I will NOT ruin my reputation by selling your data to a third party.

I just believe that requiring double opt-in to subscribe to any email-based system is a win for both parties: You are safe from unintentionally subscribing and I can be confident that you actually own the email address and want to receive the newsletter I send you :)
