Wow, I found it again. In the new members technical section Icemark has posted a sticky of terms and abbreviations. It's way worth looking up. Perhaps with all the assigned reading one is guided to, this could be one of them, as I chased around a while to happen upon it for a second time. I copy/pasted it into a text document to print/study. I'm feeling more literate already.

 

There are a few of those around. Usually in the FAQ threads for each generation. Keep on learning.

 

I'm starting to get my legs here...
