When I try to forward, it only lets me chose SMS addresses. Although I did find that I can copy the text and paste it into an email and then send the email. Not an ideal solution, but could work.
when it asks for an SMS address, try typing in your email address and see what happens. (change from 123 to abc [numbers to letters]), and i think it should work. if not, then copy and paste is the best way to go.
