To come off the end, you can simply turn off and land. Coming off in the middle, though is a bit different. You have to ollie out, and bring the board off and around with your front foot (ollie out off the end for bonus style points). Land with all 4 wheels at once, don't shred, and roll away stylin'.

Backside feeble

First learn backside 50-50s and 5-0s. Ride at the object with a good amount of speed. Ollie on to the object like you're doing a backside 50-50, but right before both trucks make contact, push the front one over the bar by straightening your front leg. Lean back with all your weight on the back truck (the weight placement is very similar to a 5-0, but with your foot pointing the nose down) and hold that position while powering through the grind. At the end, let your nose come up so your board is parallel with the ground right as you come off. Ride away with both feet over the truck bolts, clean as a whistle. Feeble grinds can be taken to all kinds of obstacles, and is a popular handrail trick. Once you learn how to lock in to them, they're easier to control than boardslides. Now get to feeblin!

Frontside nosebluntslide

You're going to want to gather some decent speed for this one. It's not the kinda trick you can just get onto and hang out until you come off. You've got to earn it. Your front foot should be close enough to your nose that you can stick it on the ledge, but far enough back to let you pop a good ollie. Come at the ledge parellel. As you pop, you should shift your momentum so you're ollieng towards the ledge to get your nose locked in. It's almost like you're nose sliding the side of the ledge. Once you're on there, keep your front foot pushing that nose down and forward. If you stay balanced on the ledge, the dismount isn't too tricky. You kinda nollie out, and use your back foot to control the tail so you land riding straight. Make sure the ledge has a good coating of wax, especially on top where your wheels are sliding.

Frontside tailslide

The frontside tailslide is a trick that, although difficult, can be learned in stages and worked up to. It is useful to be comfortable with the frontside 180 ollie, though you won't need to turn around all the way. Practice landing in the tailslide position by riding at the curb slowly and ollieing frontside. Get just your tail over the curb and put your weight on that tail as you plant it on that curb, leaving your trucks and wheels hanging off the edge. Once you're comfortable landing in that position, try it with a little more speed and roll at the curb almost parallel to it. The faster you go and the more parallel you are to the curb, the longer you'll slide. Once you do get the hang of sliding, get a feel for how long you can push it before the tail slows down and locks in place. You'll want to begin shifting your weight back over the board as it slows down so that you can come off the curb with at least some speed, before it stops completely. Once you have the frontside ollie tailslide wired on curbs, take it to a ledge or something a little taller. Also, try swinging your torso frontside as you ollie into the tailside position, and instead of shifting your weight back over the nose to come off the object, push the tail ahead of you to finish the frontside 180 motion initiated at the start of the trick.

Frontside lipslide

In order to execute the very popular and attractive lipslide, learn boardslides and frontside 180s first. Approach the obstacle as you would for a 50-50. Pop your ollie and start turning yourself (and your board) frontside, making sure your back truck is high enough to go over the obstacle. Once you are hovering above the object, perpendicular to it, land in the boardslide position. From here on out, it's just like the ol' boardslide; just cruise along that rail or ledge as long as you can and come off like you would a boardslide. No, wait, scratch that. If you're bustin' this lipslide on a ledge, then your back wheels should be sliding along on top of the ledge. When it comes time to come off the ledge, put pressure on your tail so that all your weight is on your back two wheels. Then turn your board forward and roll off of the end of the ledge. There, that's better.

Backside 5-0

Approach the obstacle with a good amount of speed, because all the friction is on your back truck, whereas in a 50-50, your weight is distributed between both trucks. So, go a bit faster that you would for a 50-50, because you need to push through, and balance through it. Ollie next to the obstacle, and try to keep your nose a bit higher than your tail. When you are over the obstacle, put your back truck down, and balance. Now you should be balancing, like a manual, but with a bit of resistance, depending on how waxy the obstacle is. Just relax, and enjoy the ride. Ideally, your tail should not be touching, but chances are it will at first. If you had enough speed, you should just cruise off the end. If you're coming out early, you need to ollie and turn a bit. It's weird at first, but you will get the hang of it.
