comment projective map from $\overline{\mathcal{M}}_{0,n}$
@Hacon: yes you are right, it was probably me who expressed badly the question. I will re-edit eventually. My point is that I am not that good enough at birational geometry to understand what kind of singularity will I get just by knowing the set of exceptional curves (or divisors, if you prefer).

comment projective map from $\overline{\mathcal{M}}_{0,n}$
@Jason: and would normality be enough, in your opinion?

comment Top specialized journals
do you really think that J Topology is at the level of JDG or G&T? my (limited) perception is that it is a little lower

comment symmetric theta structures and arithmetic subgroups
good point! it is not completely clear to me yet... :D just kidding: as I have edited, the reasons for which there are different actions of the modular groups on characteristics (one or two orbits) -depending on the level - is still unclear to me.

Yes I meant the finite field of order 2, thank you! What is the precise book reference that you suggest?
