Showing only Approved Metapedia Terms

This question is two fold:

1) Is there a way to only show approved metapedia terms?

2) How have others managed their metapedia terms in a "multi-tier" environment (dev / qa / prod)? Do you promote your terms / changes through different environments or do you manage your terms in one environment?  What is SAPs suggested best practice here?

I'm trying to achieve the scenario where metapedia users only see approved terms. Right now we are controlling this through drafting the terms in one environment and then exporting / importing them into another environment as approved.

Thanks!!
