I used to use an e-mail sender address of "username-1." I do not any
more. I still use the email account, but with "username1" instead. How
do I delete username-1 from the list of names that appear when I send an
Open Seamonkey Mail.
Open up the preferences for Mail&Newsgroup-Accounts.
Select your account by clicking on it.
There's a button to manage identityies at the bottom right.
Click on it to add/delete/modify your identity.
