What have I missed?

[Era Scarecrow via Digitalmars-d]

  But naturally before i can do anything i need to re-familiarize 
myself with Git and GitHub... and immediately remember why i 
pretty much rage-quit 18 months ago...

  Is there anyone who i can refer to via IM/PM or some quick 
method when i start using this stuff to get it sorted out (rather 
than these forums)?

  Although it's pretty likely i'll either start a brand new 
fork/repository of phobos or destroy my current saved changes 
(commits, fixes, everything) as they will be a pain to figure out 
since i never could get it to work last time... even after i 
rebased it last time...
