You can ask me anything and I will try my best to answer. As a problem author of a successful round and an Master I think I am qualified to do AMA.

I was randomly doing some searching on the search bar on CF, and a very strange thing happened
Obviously, there should be results of "April fools" on CF. I have tested that, if I change to sort by popularity or time, it also does not show results. I also tried other things to search, and the only thing it shows is a person of the username I searched, such as follows:
I also reproduced it on my phone, so it should not be a problem on my end (unless it is that both my computer and my phone has a problem) Can MikeMirzayanov have a look on it?
I am a purple coder, who desperately want to get to orange in order to write a CF round. Sadly, despite my attempts, I still haven’t succeeded.
During summer, or if the next day does not have school, I can stay up late (my time zone is GMT+8) and participate in the round. But as I become increasingly desperate, I want to find a way to participate Round 821 also, which is on a Monday, and not get sleep deprived for the next day at school. The more rounds I participate, (hopefully) the quicker I can become orange.
Now, I want some suggestions for me to be able to participate a CF round and still be able to wake up early for the next day of school and not doze off during lessons. Can anyone give any suggestions?
