Hello, am planning my fencing work and am wondering why it seems standard practice to fix/ slot fence panels between posts instead of actually fixing to face/ front of the posts. I.e. if I'm using 100mm wooden posts then each panel could be fixed 50mm to front of posts butted up to next panel? Thinking this may make it structurally stronger and avoid having to slot/fix panels, but never see it done like this. cheers.
