Information about grid hydrodynamics

Information about tidal captures

The role of binary-single and binary-binary interactions as channels for collisions to happen

The results of the author's ~15000 collision simulations, as promised so many times! And some software to use this data in stellar dynamics code...

More complete discusdsion of the various astrophysical contexts in which collisions play a role, with references.

Complete lists of references to SPH and grid collision papers; comment all references.

Should other stellar hydrodynamical processes be included (common envelope...)?

Should BH--BH be included?

More detailed information about the hydrodynamics of collisions, in physical terms

Add something about few-body models of collisions (Livne & Tuchman 1988 for MS-Giant...)
