All tasks were made by me, but gepardo helped me a lot with the last two tasks, probably these tasks wouldn't have appeared if he didn't help me.

My thanks to:

Hello Codeforces! Recently I've become an author of a Codeforces Round #672 (Div. 2) (it will take place soon). Immedaitely after placing my contest in a timetable, I have been attacked by the messages of a following content:

"Hello, can I be a tester of your codeforces round? I want to gain experience in testing CF rounds" etc.

I want to tell you something. If you didn't know, the process of making and testing the round looks like this:

1) Author makes codeforces round. Of course, he/she also needs to test his/her round carefully.

2) When this work is done, round coordinator invites some people to test your round. Both author and coordinator can choose testers at this stage.

3) When testers looked through the round and did their work, round can be placed into the timetable. After this no testers required.

So, now, I hope, now you know that when contest is already done and scheduled, it makes no sense to write such messages to authors. By the way, this messages are not annoying. I just want you to not to waste your time.
