When I use :GetChildren() , what is it's argument?
How can I use this to check for a certain thing within a player?
would it basically be using a PlayerAdded event and then use IsA(ClassNameHere) ? I will be looking for a classname not name.
Should I be using a Generic for loop such as for i,v in pairs do ?
Any information that can be given would be helpful!
I have looked in the huge list within studio and searched some things in Wiki and couldn't find what I wanted.

The 'GetChildren' method is like the deprecated 'children' method; It creates a table of the current Children within the Parent [Parent:GetChildren()]. http://wiki.roblox.com/index.php?title=API:Class/Instance/GetChildren
I don't see what's unclear about the wiki.
