We'll just take off some points :)“Heres how IRC and the routing daemon work”We know how they work!“We did some testing, it seemed to work”Maybe we did some testing, and it didn't seem to work, you didn't prove it to us, we can't give you points for “seeming to work” and we don't have a spare hour to regenerate your topology and messages --> scripts!“Heres a picture of a topology we setup...”How pretty! But where are your configuration files for it? --> scripts!?“We have no scripts, but we did this test..... this test.... and this test....”Great, but it would take us 20 minutes to read about all your tests, and a half hour to reproduce them --> scripts!!Documentation – What We Want !!!!!!!

No team spent nearly as much time on the daemon as it was worth, plus we found it more fair!Start early!! (do you understand why now?)More Suggestions for Project 2Major functionality is what countsWaste 3 days getting LIST to work properly --> +1 pointSpend 3 days getting routing to work--> + 20 pointsWe care about you getting the major understandings, not so much about the little details.We even graded your server using checkpoint 2!Get to know your partners work habits earlySUBMIT PROBLEMS TO US ASAPWe are caring and understanding people :)Use IRC!
