My Email IDs problem

I work with Firefox 3.x and try to use the mail option. At the "My Email ID" there is a email adres locked but it does not work. I do not have the resend button for the email (also not visible in IE). and I can't make a second adress....

I wanted to mail 2 documents out of the writer by going to Gollaborate > email out but this also does not work for me
