Ditto. Watch the spam Zilea. If you have a real question about the topic, rephrase it to something bigger than two words.
On topic though, even if this is a week old, Melee is changing in 1.1 . Head on collisions will be determined by ki and not ping now, so keep conservative. However, as you will learn with time, head on collisions are not all that melee is about. Try experimenting with teleport and see if you can start hitting people from the side. Remember: Always keep moving.
Edit- I think I'm going to go ahead and move this to the newbie section. The help forum is more for actual gameplay issues than playing power, or questions on how to improve your gameplay.
