I see a position called "mast-col" and I saw one post here that said it's just another position. I'm assuming it is named mast-col for a reason but I'm drawing a blank as to what it would mean. Masthead-column? Makes no sense, since it's not at the top of the page where a masthead would normally be; and wouldn't the logo area be the masthead? I want to work *with* the intended purpose of the positions as much as possible (since I've found making it up as I go along often creates problems down the road). Can anyone shed any light on why this position is called mast-col and what its intended use is?

Many thanks!
