I think I understand it now that I quoted this and saw the coding behind it. Thanks!
You don't need to use the code.
It's just as simple as mentioning a friend on Facebook comments, "@" + "Name".
You don't need to use the [mention=userid][ntion] that makes it real hard to keep on with members.
Try tagging me below "@" + "Ameer" without the quotation marks, and no spaces.
