Thank you SO MUCH! I'm a map maker, so this is very helpful to me. I always refer to this page, which makes the effect command seem so much simpler than the wiki does. I used to think the effect command was so complex and difficult to use. This is so simple, and I use it all the time.
The Prerelease for 1.8, or the Bountiful Update, was just released today, so here is the list.
4. Mining Fatigue
6. Instant Health
7. Instant Damage
8. Jump Boost
11. Resistance (You should know why I love this. Back in 1.5 I got myself a high level of resistance with invisibility and jump boost, and I WAS LITERALY INVINCIBLE! NO KIDDING! EVEN WITH THE /kill COMMAND!)
