At Jon's request, I am expanding a comment into an answer.
Jon, I'm sorry -- I wish I could give a different answer. But I can't.
Summary
I do not recommend this site for Jews now because of the religious nature of the site. Participation by Jews is actively harmful.
If you are considering participating there, particularly to contribute answers that teach torah, I strongly recommend that you seek rabbinic guidance first. I have now done so (belatedly) and no longer participate there. If you do participate, I recommend a short disclaimer on your answers; this practice is permitted by SE (so long as you don't use it as a soapbox, of course).1
Details
I became active on Biblical Hermeneutics early on (in 2011) and was for a time the #2 user by reputation. There are a lot of questions that don't apply to us since they consider Christian books too, but it seemed like I could provide useful Jewish answers to Tanakh questions, and since the site claimed not to have a doctrinal basis (as noted in this question, and also in the site's "about" page and numerous places on meta), that seemed like an ok thing to do. I received positive feedback from users who only ever learned the Christian spins on our texts and aren't able to read the original Hebrew, so I thought I was doing a good thing by countering some mistaken notions that Christians sometimes spread. And there are some smart, educated people on BH who I enjoy(ed) interacting with.
However, I no longer recommend this site for Jews. Why? Because that doctrinal/dogmatic neutrality hasn't worked out in practice. Despite the charter, and despite a massively up-voted meta post saying "Any discussion of beliefs, doctrines or theology belongs on Christianity.SE", too many answers (and sometimes questions) assert Christian truth claims that are decidedly counter to the Tanakh (now with explicit permission to do so). Efforts to move them toward neutral or descriptive statements failed. Even a request that offensive claims should be relevant and supported was resisted. The environment became hostile over time; replacement theology, reading Jesus into the Tanakh, and sermonizing are common there now, and the vast majority of the users don't see the problem. The ones who do see it have been unable to correct it.
About two years after I began participating, I finally realized that this is no place for Jews. Not only was I not doing any good by participating there, but I was most likely doing harm (later confirmed) -- I was teaching torah in an idolatrous setting, an online church. That's no good, so I left.
