How to join more than two strings?

[Kurt Holm]

I'm using join, but is only able to join two strings. How do I join more than two strings?

It's a mutator block...you need to click the little blue gear icon and add more "items" to the block.

To join two or more strings use the "join" block. By default it let's you two strings, if you need to join more then click the blue square and add more string by dropping them in under the two auto generated ones.
