Introduction from PA

I've prowled around here for about a week and I'm thinking breadmaking might be my next obssession. I happen to be a SAHM who homeschools, as well as an author, who writes cozy mysteries for Barbour Publishing. There are a few terms that I can't seem to understand that are used on this site. One is "preferment" the other is "crumb". There might be a few others, which leads to my next question, do you all have a dictionary of terms for newbies entering the breadmaking world?
