If I'm right in thinking you want your wife's email under your login you have to create a new identity in oe which you can do if you go to file-identities-add new identity, then this will take you through a wizard to do this, askng for pop3 acount name and smpt info etc etc
Then when you or your wife wants to check email you open up oe and click on file then switch identities, click on your wife's name then ok and you should be able to receive her mail only, or visa versa.
I assume you are using oe6.
Good luck bretsky;0)
ps:hope I have got hold of the right end of the stick here!!!!
