I am considering creating one alternate character for me and one for my husband. Part of this is so that we can help get things for others who are not able to, and part is curiosity. But, I've been very hesitant to create a mule because I may not want to continue to have one (I have six different logins to remember just for my job!). Once a mule is created, what care and feeding does it require? If you decide you don't want it any more, how do you "kill it"? Is it proper to use the same email address for a mule as you do for your regular character? Anything else we should know?
