Renan, I'm not saying that a manager MUST post the Entry List, there are much more important things in life for sure. What I am saying is that, if you know you're going to be busy in the weekend, ask someone to post an Entry List for you, I'm sure anyone commited to your tournament would have helped you.
Just as a small remark, you could have done it yourself without the manager asking. I was late with making the draw in Orleans and someone just made the draw, which helped me a lot! So if you saw that this problem would arise, you could ask for it in the thread before the deadline (don't know if you did) and otherwise make it yourself.
But I completely agree that an entrylist should be made before the deadline!
