Hello,
If you read the old threads you could see that people were looking to get an email to obtain an information to solve the level but now you won’t find it in your email.
Before the site was a little different - its name was Hackthis!! - and this information was included in email you could receive from the website. So in order to get an email poeple were asking for answer to their post because after someone replied you were receiving an email notification and you could complete the level.
So now, almost - maybe all - older threads are outdated, if you want to ask for help it’s probably better if you create a new thread or answer to this one to avoid to raise the old threads.
Thanks and have fun !
