sPHENIX cold QCD topical group

[Ralf Seidl <rseidl AT rcf.rhic.bnl.gov>]

Hi Greg,

thanks for the update, the illustrations look really nice now.

About the two remaining comments from Charles, I guess you could make it 
"p+p Collisions" and it should be fine. You Capitalize every word in the 
title so the capital c should be fine.

For the Q1,Q2, it might be good to give the reader that connection 
explicitly, ie Q1 (~kT or P_hT) << Q2 (P_T or Q^2)

After these changes you have my ok to print the poster, but check with 
Caro as well.

Cheers,

Ralf
