I think it's okay for info in the intro book to crossover somewhat with the information online. The book will 1) put a ton of info in one place for reference and 2) be organized in a way the online stuff is not.
I would imagine an introduction to the gods, a few major myths (The Founding of the West, Ava at the Gate), some devotional poetry and prayers, a basic calendar and ritual structure... some of which I think will continue to be fleshed out next year and in the years to come.
Perhaps we can go into 2015 mindful of the work the needs to be done to make a cohesive structure of the Otherfaith that is accessible to a wider variety of people. For example, I found an entry into the Otherfaith because I knew Aine and personally find creative worldbuilding as very rewarding work - but not everyone is me, and I can think of a lot of what I'd *like* to see the Otherfaith have that it hasn't had a chance to build yet.
I'm actually really excited with Reunion; there's a lot of content being created that's helping flesh out the holiday in terms of mythology and community involvement. I'd like to see that continue with other major holidays in the faith, especially the Apotheosis of the Dierne.Â
One thing I feel that's lacking is ritual and/or liturgy - which, given the nature of the Otherfaith at present (and the current lineup of folks involved) isn't necessarily a bad thing! But it would be nice this year to experiment between the handful of us and have a list of rituals or devotional practices or whatever that are already in place to offer potentially interested newbies.
Finally - and maybe this is completely separate from the idea of an intro book - I'd like to see some more info about Otherfaith spirit work or mysticism or whatever.
