title: Google spreadsheets. Do something when cell contains E-mail Adress
body: <p>I've got a cell which could contain an E-mail address, plain text (not an E-mail address) or be empty. If the cell contains an E-mail address I want to copy everyting in that cell to a diffrent cell, and when it doesn't contain an E-mail adress I want to copy that text to another diffrent cell (diffrent form both the E-mail cell and the original cell). If it's empty I don't want to do anyting. How would I achieve this?</p>

  <p>Thanks in advance.</p>
