    Hi Ramiro,
    Here are some comments to your abstract. Sorry it has taken me so long 
    to get to it, I hope it helps even though it is
    so late.
    Comments:
    Title:  I dislike the use of "most forward rapidities" since we do not 
    measure the MOST forward.  In fact, we only measure at y~3 (if memory 
    serves).  Why not just say forward rapidities?
    Text:  I do not know if there is any formal limit, but I think that the 
    abstract is too long.   The introduction seems wordy, but
    I don't know what you want to cut out.   I suggest the following:
    
    The very early stages fo heavy ion collisions at RHIC can be described 
    by partonic degrees of freedom.  The energies achieved are sufficient 
    to study parton distribution functions at x$\approx 0$.  HERA deep 
    inelastic scattering results indicate that the gluon distribution 
    function saturates and enters a non--linear regime as x approaches 0.  
    Recent theoretical work has shown that this limiting behaviour is 
    reached at lower energies with heavier targets.
    
    Here, you lose me.  you say that the proper scale grows as a power of 
    A, but not what the scale is.  Also, you say the "new medium" is the 
    CGC,  but it is not clear (to my simple mind) what you mean.
    Can you make this so clear that even I can understand?  Not a simple 
    task, I am afraid...
    
    I pick up again in what should be a new paragraph starting with
    
    During Run III, RHIC provided d+Au and p+p collisions at 
    $\sqrt{s_{NN}}= 200$ GeV.  The BRAHMS collaboration collected large 
    data samples at $y=0$ and $y_\pi=3$.  In this talk, we will present 
    comparisons of transverse momentum spectra between d+Au and p+o 
    collisions for charged hadrons and identified hadrons at these 
    rapidities.  These results will also be compared with available model 
    calculations. Rapidity density distributions for different transverse 
    momentum ranges will be presented and discussed with the context of the 
    possible formation of the CGC at RHIC.
    
    
    Finally, a question: how much of this analysis has been done, and how 
    much remains?
    Best regards,
    Ian
