New particle system

Leaved Blender for months and new version come. New particle system looks good but have some problem about it. I saw the official avi tutorial but need a more detailed one, is it there?

A specific problem is I used texture give start speed to particles. It’s work, but not observe the UV coordinate white correctly show in mesh. Any idea about it?

This should be in the Support forum, specificly here:

I think I heard that UV textures arn’t observed with the particles, which I heard from something that had to do with Plumiferos.
