I think you will find quite the range in the forum, religiously.  It's pretty fun.  At least I think so -- I like being around diversity.
On a scale of 1 to 10, 1 being a psychopath without conscience and 10 being Amish, I'm probably about a 9.  I'm a revert to Judaism, meaning that my family had left the tribe and become Christian, and I was Christian for many years, but I returned to Judaism.  In terms of observance, you can call me Orthodox-lite, or perhaps Conservadox. I pretty much aspire to an Orthodox level of observance, but in reality I break a few laws here and there: for example, I routinely violate Shabbat by using my computer.  But pretty much I try to keep the 613 commandments.  
You will find that Jews don't care that much about beliefs -- what matters is your behavior.  I don't really have a lot of belefs.  I believe in G-d, but it is hard for me to talk about a being that is so utterly beyond my comprehension.  I will say this much:  G-d is the Creator of all that is, and for some reason, He CARES about how we treat each other.  I do believe He interacts with us, but in ways that are hard to pin down exactly what's going on.  I'm not concerned about the historicity of the sacred texts as I am about the lessons they teach.  Like, I think that G-d gave us the Torah, but did it go down exactly as recorded in Exodus?  How should I know?  It doesn't matter.
I have studied almost all the major religions in the world, and have a preferential fondness for Taoism and Native American spirituality.  I think that every person who considers themselves educated will be Bible-literate.  I think of the Lord of the Rings as my "other bible."  Despite the obvious disagreements between various religions, I think a lot can be gained from studying their wisdom.  The sages say, "Let the wisdom of the nations be your wisdom, but do not let their Torah be your Torah."
What I have difficulty with is understanding secular thinking.  While the religious man makes a distinction between the sacred and the profane, the secular man doesn't believe anything is sacred.  When I try to imagine a life without festivals and sacred days, without rites of passage, without anything sacred, it's like imagining in black and white.  Have you ever read "The Sacred and the Profane"?  It's a classic text for undertanding the difference between religious and secular thinking.
A word on agnosticism:  Everyone who has a good brain has doubts.  The theist sometimes wonders if there is no G-d.  The atheist sometimes wonders, what if there is a G-d after all.  I don't think the fact that we never know anything for sure makes us agnostics.  I will classify as agnostic someone who not only says they don't know, but they LIVE THEIR LIFE inconsistantly as if G-d may OR may not exist.  Again, we return to the Jewish emphasis on actions:  If you say you are an atheist but you live your life AS THOUGH G-d exists, I think of you as a theist.  If you say you are a theist, but live your life AS THOUGH there were no G-d, I say you are not believer at all.  And YES, I do know a lot of religious atheists (meaning they live as theists even though they don't believe in G-d) -- I pray with them every Friday night.
Shalom!!!!!
