Let me first begin by saying that I WILL be purchasing XenForo. After being with VB for well over 11 years I have had enough of the constant hacks and security issues I am experiencing. I can't take it any more. Right now, I am simply trying to become familiar with what I might have to deal with adjusting to XenForo once I make the purchase. One of the primary issues for me is ad management. Is this something that comes already installed with XF or will I have to include an add on? If so, is there a cost for the add on? And where will I be able to place the ads? Also, is the responsive design a feature the comes with the latest version or is that something that will require modification? Thanks in advance.
