OK, so it doesn’t matter what you have converted from and to, etc, but if at some point you have made major changes to your faith, vote Yes in the Poll and write in the topic (if you like) what you’ve gone from and to. (In general, try to keep this to really major changes, so TEC > ACNA or ELCA > LCMS might not quite count, but if you think it required a major reconfiguration of your beliefs, please do).
For me it was Atheism > Christianity (Anglicanism).
I was an atheist for a long time, then I sort of stopped thinking about it. Then I spent about three years studying and pondering Christianity before I finally got formally initiated.
