2 summers ago we put up a new fence in the backyard. The yard backs onto a road so I decided to install a gate in the left corner of the yard. I used 4x4's for the posts, they are at least 3 feet in the ground filled with concrete. The problem I have is with the gate - we built it ourselves and I will admit it's pretty sturdy but I feel like it's too much weight for the posts to support. The ground also sloped where the gate is, so the gate is always hanging and is not supported by the earth due to clearance. I plan on fixing the slope and putting some gate wheels on it, but I still need to fix the 4x4 which like I said is starting to lean. What would be your best suggestion for supporting the 4x4?

I need to install a stockade fence. Since I have a pool the horizontal pieces must go on my side, the inside. At the back of my backyard is my neighbors fence. It is a 4 foot chain link fence and then, in the inside of that for him, he attached a stockade fence to it. But my town requires me to have my own fence. Anyway, my backyard is not very spacious and I want squeeze every inch I can so I want to put my stockade right up to his chain link--maybe just an inch or two of space. So, to be as economical as possible with space, I figured i would notch my 4x4 posts so that the horizontal 2x3 can sit in them. then I can toe-nail them in since I wont be able to nail in from behind (because of the other stockade fence) or maybe screw through 4x4 into the 2x3 . Note: neighbor is not friendly so I cannot just connect my fence to his chain link--which would make the most sense. My concern is that the fence posts will warp. 4x4s seem to warp pretty easy to begin with, but if notched out I am afraid they will warp even more. Should I be concerned?
