Hey,

There are a number of reasons to have things validated by email address. =
 The best reason is so that all the different characters someone makes ar=
e all under the same umbrella, and someone doesn't just forget they have =

Of course, whether someone is allowed to have those extra characters at a=
ll is purely a matter of rules of your particular MUD.
