So, Im looking to do some unregs, and Im just wondering if theres a simple way of like adding @hotmail.com, or @yahoo.com to a bunch of different words/users.

Example

If I had a list like:

InfamousJoe
Bettser
Carrot
Bammeh
John

And I wanted to just simply add @hotmail.com to each name... what would be the easiest way of doing this?
