Can you explain what a troll is? And while you're at it, could you explain what a bump is, and common acronyms such as ROFL...., etc? as for your comment, many of the comments so far do seem to display a large degree of ignorance.
A "bump" is to bring activity to the thread to keep it active so others will see it.
"ROFL" is rolling on the floor laughing
A "troll" is someone that gets on a thread to get everyone up in arms, angry etc... Basically fishing for an intense response. Usually by someone new that only wants to disrupt.
