1) If only 1 newletter with no addional categories is available
FE[tt_address][module_sys_dmail_category][0] would be used to assign to 
the newsletter

2) If you add more categories and selection is on a different page add 
the value of FE[tt_address][module_sys_dmail_category] in a hidden field 
   in the dmail subscription template.
