The Track-To constraint lets you influence the Rotation of the constrained object by making it track a target with one of the constrained object's axis.

This constraint copies the rotation of the target. As simple as that. It can be an object or a bone.

The Copy Location constraint does as the name states: it will copy the location of the target to the source (constrained object). Less Influence will drag the constrained object less and less to the target.

If it's an armature, a new field will appear to let you tell which bone will be the target. Don't forget TABKEY completion while writing the name of your object/bone!

You can tell Blender to work only on the selected axis. Many uses are possible :)

A constraint is what makes everything easier, magic, automatic, customized (add more words here) in a rig. It tells a bone or an object to do something special based on the position of another object, and the position of the constrained object itself. There are many constraint types for you to play with. Most will work everywhere but, the IK solver will only be available in the Armature Editmode or Posemode.

Here we will attempt to explain my recent dealings with using Blender Shape Keys to produce convincing lip-sync (Lip-synchronization, ie: "speech") for simple, humanoid characters.

Shape keys are modifications of the original mesh that you can animate and mix with each other. Previously called Relative Vertex Keys (RVK), one of their major uses is to create facial expressions.

Vertex groups are specific to the Mesh object and can be modified in Editmode. Let's learn more about them, with the help of this tutorial.

Envelope is a new visual tool to help you rig your characters faster and easier. It can often save you a lot of time. Each bone has a special area around it, allowing you to tell Blender what part of the geometry will follow each bone. This zone is customizable so you can move, scale and blend them together.

This is a tutorial about how to tell Blender: "use this armature to deform this mesh".

Posemode is a very versatile place where you Animate your character, create and manage constraints and apply your rig to your character.
