As the forum is turning 5 years old I hid a little present in the forum for the one who will find it. The one who finds the secret puzzle solution will get a reward 
This is inspired by these puzzle games where people need to find something in the internet which is hidden there.
As I do not know if it is easy or not I will give occassional hints and answer questions here if I think this might be helpful.
Attention to @kaya - As you can see more as the “normal” user you unfortunately can’t participate. But you are invited to still look for the way this is going to be solved. 
And now let’s go and find it
