"INTREP" = Intelligence Report - from my old artillery days. References an entry that I disagree with, as anything positive about Obama would be an INTREP. Likewise, secularism, naturalism, atheism, etc.
"YEC" = Young Earth Creationist - somehow, the entry assumes an old Earth Worldview.
I use these as markers for my study and class preparation.
Thanks. It would have taken me about 4.5 billion years to have figured it out! :)
