Look at Array#join

Sure, with some simple regexes, try out:

<this is a joke>
puts myarray.inspect.to_s.sub(/^\[/, "").sub(/\]$/, "").gsub('"', "")
</this is a joke>

But to be serious, you're looking for the "join" method, like this:

puts myarray.join(", ")

Robert, try

myarray.join(", ")

It will take every item in the array and join it using what you put in 
parentheses. It returns a string, so what you'll really get back is
"test1, test3, test4, test5"

If you look at the Ruby docs for Arrays you'll find some other useful 
methods you can call on them.
