add "take screenshots" on the tutorial

Suggestion: Add a sign for builders on the tutorial that says "take screenshots of all transactions to avoid scams"

Reason:
I was scammed on my 2nd day on ECC, none of this would have happen if there was a sign that said "take pictures of all transactions to avoid scams" in order to prevent this we need a something on the tutorial that says this, so that way it wont happen to any other newbies like me.

Other Information:
be careful dealing with evanj421, he may or may have not scammed me... but you didn't hear it from me

 

i know now but i didn't know there was a wiki when i started, and there's a good chance new users wont know either or at least bother to check, i just think its safer to put it on the tutorial
