TextExt Plugin and Posted Form Data

TextExt Plugin and Posted Form Data

I have setup a jquery plugin on my site that came from here :  http://textextjs.com/

It provides autosuggest functionality for a textarea. The user starts typing, then when they select/click an item from the dropdown that appears with the suggestions, it appears in the textarea as a tag. 

Then when they press the submit button, the form data is posted in this format :

["tag1","tag2","tag3"]

However, the problem I have is that users will often enter text in the textarea without selecting an item from the dropdown menu. Then when they submit the form, the text they entered is not visible in the posted data, i.e the posted data looks like this :

[]

I need tagged and non tagged data to show up in the posted form value. I am almost certain there is an option somewhere I can configure in the .js files for the plugin for this. My best guess at the moment would be the files textext.core.js and/or home.js. 

I know, I should be able to read through the manual and work it out myself ( http://textextjs.com/manual/index.html) but jquery is not one of my strengths so I have spent a long time trying without any luck.

Thankyou :)
