The 4 stages of collaboration:

- Stage1:
Hey dude, I setup some online docs and left some instructions / discussion points in slack, but you haven't been logged in. Can you login and have a look when you get a chance?

- Stage 2:
Oh Hey, did you ever get a chance to have a look at those docs / discussion points?

- Stage 3:
Hey, look this is due by close of business tomorrow, can you take spend an hour on it before you leave?

- Stage 4:
*loads shotgun* HEY YOU! ... sit here, login to that ..... STOP CRYING AND HURRY UP ..... see that right there? thats missing your input, you have 15 minutes left ... GO!

I'm fast approaching stage 4 and loading my efficiency shotgun as we speak.
