Seems like a good idea, but Mike is in Russia, and mailing submissions from USA to Russia is not possible because of the war and airline restrictions. I have a few ideas for how to fix this:

• Mike moves out of Russia
• Stop the war
• Move everyone who uses codeforces into Russia
• Send emails to Mike instead
• Mike creates a website which automatically judges submissions
• Use scanned answer sheets like the AMC 8
• We call Mike through telephone and read our submission verbally
• Use carrier pigeons for O(1) submission delay
• Mike makes a google spreadsheet, we mark the problems off as we solve them.
• We go to Mike's house whenever we want to submit, and politely ask him to mark the problem as Accepted

感觉很可行啊，洛谷可以效仿 XD
