I want to add nested content spinning functionality to this plugin. In the current version you could do this:

{Hello|Hi|Hey|Howdy}

but not this:

{Example {One|Two|Three}|Sample {This|That|The Other}}

Any idea how do do it?

It clearly says under the FAQ's that the plugin does not support nested content spinning:

"Does this plugin support nested content spins?
No, currently, the plugin does not. That means you won't be able to do something like {{Example {{One|Two|Three}}|Sample {{This|That|The Other}}}}. It will be added in the future, as this is very neat functionality."

What part of my post made you believe that I am not aware of that?

Anyways, I have coded a new plugin that supports nested content spins.

I no longer need help on this.

Thanks.
