you can make two scripts.
one(for your first account)
code:
function OnEvent_ContactNameChange(mail,isim) {
if (mail == "yourSECONDmail@hotmail.com") { Messenger.MyName = isim; }
}
two(for your second account)
code:
function OnEvent_ContactNameChange(mail,isim) {
if (mail == "yourFIRSTmail@hotmail.com") { Messenger.MyName = isim; }
}
will it work?
i didn't test it
(sorry for my english)
