Let me know when you have a few minutes.  I want to go over a few of the questions you had which I haven't yet done anything with.
You could also use `#inject` to use the string as an accumulator.

If you need to concatenate, use the `<<` operator instead of the `+=` operator.  `+=` takes two strings and creates a third string that is the combination of the two. `<<` instead modifies the original string.
```
accumulator << string_to_be_appended    # accumulator is modified, not reassigned
```
