What is Spintax

Spintax is the format (or syntax) that is used by various software spinners and article submission sites that create or use spun articles. There are various spintax formats depending on what software/services you use
Here is a link explaining it http://umstrategies.com/what-is-spintax/

For example, if I wanted to say hello 
Spintax would be something like:

{hi|Hello|how are you|nice to meet you|glad we linked up|hey there}

this means that it will randomly select something from the above
Hi
Hello
how are you
nice to meet you
glad we linked up
hey there

spintax is encapsulated inside curl brackets,

and each randomized item that it can select is placed with a line pipe | between each one inside the curly brackets.
