When playing Yahoo games, how do I get rid of ISP name with screen ID?

Answer 1

if this is 1st id you registered with on games,you can not change it. you can go to edit my profiles and make up to 4 more ids, each starts as provisional.

Answer 2

Just do this. I did and I like it. I just put the dot between my first and last name. I did the same thing as you when I started out. Mail Options:

Go to Yahoo Mail and go for it!!!
Management
Mail Addresses
We've added the dot into our email addresses so you can get the address you've always wanted. Use it just like your existing Yahoo! ID. Also retrieve mail from your other (POP) accounts into your Yahoo! Mailbox
