I've created a website called OrthodoxConvert.com
. It does not have a discussion board or a mailing list, nor do I have plans to have either one. The main purpose is just to be a central place for people to tell the story of how they became an Orthodox Christian. In the future, I also have plans for a FAQ posed by potential converts and possibly an apologetics section. However, the main point is just to tell the conversion stories.
If you would like to tell your story, see the instructions at the site.
