Can be used instead of texarea and then passed trough form someh
You could better use:
NOTE: I changed innerHTML to innerText. This way you don't get HTML elements and text but only text.
Example: I submited "text", innerHTML gives the value: "\r\n text". It filters out "text" but it's longer then 4 characters.
innerText gives the value "text".
This is useful if you want to count the characters.
