Adding 'Identities' to Webmail

[#1]

Can anyone tell me how to create/add a new identity in Webmail?  I'd like to be able to send outgoing emails with different forms of my name depending on who I'm writing to.  I can see how to edit names, but not create one...
Thanks!

You'd need to login to the member centre and got to 'Manage my mail' - Icon in middle of this screen: https://portal.plus.net/my.html?action=myemail&s=1&redirected=yes&?membermenu=emailsettings

You don't need to change your mail settings for this,  unless you want to create a corresponding mailbox, rather than use the catchall
On the Identities page in the Webmail Personal Settings  (which is where you're looking I presume),  you need to click on the + icon in the bottom left of the list.

Thanks! That's it sorted...simple really
