Thanks for the explanation. So, I can just copy-paste the code to my signatures space and then open a thread as you described? Should I open the thread before or after I make some posts in other forums? And should I make reports daily or weekly or what? And what if my referrer (the person I join under) is different with the person who guided me about the signature? Whose username should I write?
Well, it's up to you whose name shall you write as the signature offer referrer. But it's better if you put the referrer name whom under you signed up, so that he won't feel bad. Even dada need not to confuse why you have written different name for signature offer.

About the offer, you can create the thread "drowned bonuses" as soon as you place links in your signatures.
