Problem regarding username in MCreator test mod

Hello Everyone!

This is shizz_IZY, I wanted to change my username in the test mod of MCreator, when I searched for it on Wikipedia it showed me many results from mcreator.net, I found out that it is actually not possible but u can do it anyways by posting a request. So, I really had to change my username for some reason, so I posted a request. 

Now I want to know when am I going to get the answer to that request also How am I going to use it or apply it....

It will be very nice if you could help me out with this thing.

Thanks :)
