Is there a general email address that can be used for gathering information and asking questions?

The website is translated into 999 languages (yes - 999 😊) so it is very accessible to all and easy to navigate. There in an FAQ section on there as well as a variety of videos and articles (all completely free to stream or download) but you can always request a personal explanation of any questions that you may have. That request can be made via the website or by contacting a congregation directly.
