"Enter the AC-Name if your ISP requires. If you don't know it please contact "
"your ISP. In most cases you can leave it blank."
I'm puzzled of the "AC-Name" part here. I don't know what it is.
firstname.lastname@example.org believes it could be "access concentrator".
In any case, this message probably needs to be reworded. Owen's suggestion is
"Enter the access concentrator name if you have been given one by your ISP."
"In most cases you can leave it blank."
It's fixed in CVS
