In reference to document below:

I have a multi-line text box. I want to add in "text:" when entering a new line.

This can be done at any stage, as long as it is formatted before the email to clickatell is sent.

I would also like to add in if easy enough:
- character restriction for line length (not essential)

- character restriction for text box
