Please add "seeker" to how you prefer to self-identify (as in seeker of truth and fellowship)
I think it's a good idea. It gives someone who is still actively seeking to discover/define themselves as to what they believe and how they feel about religion in general, something to self-identify by, without sticking them into anything more specific (if they don't want). In combination with other terms, I think it would signify that they're actively seeking these things, but tend to identify with that other term or terms.
