[Mailman-Users] Bad Character

[David Andrews]

I manually added an address to one of my lists using the web 
UI.  There must have been a space or odd character at end of address, 
that I didn't notice.  The subscribe message indicated that:  xxx at yyy.org&nbsp
has been subscribed to .......

I can't delete the address using the web interface.  How do I remove it?
