Why Append/Remove ?

Seems simpler just recreating the whole "text" and setting the textarea
to it.

Warning Untested Sample Code --- Should not be used.

var output = "";
if (document.getElementById("checkbox1id").checked)
{
  output = output + "Text1";
}
if (document.getElementById("checkbox2id").checked)
{
  output = output + "Text2";
}
if (document.getElementById("checkbox3id").checked)
{
  output = output + "Text3";
}
if (document.getElementById("checkbox4id").checked)
{
  output = output + "Text4";
}

The variable "output" whould now be either "Text1Text2Text3Text4" if
all checkboxes are checked, or "Text2Text4" if only the 2nd and 4th are
checked ... and so on.

Set the value of the textarea to that and you're set, no need to
append/remove.
