I have a basic question for constructing my first run. I hope I'm using the right terms here--I've seen pictures where some folks have their base plates vertical (ex if 2x4, the 4" side is vertical) and others where the base plate is horizontal (4" side laying on the ground). Are there functional or cosmetic reasons to consider each option? For those that have a run where the base plate is vertical, did you toe nail the wall studs into the base plate, or did you use a long screw and screw up through the base plate and then into the wall studs? Did you use 1 wall stud or 2 in the corners? Sorry for the basic questions -- this is my first project of this sort, so I'm struggling a bit and greatly appreciate the help.
