[Asterisk-Users] REMOVE

[Benjamin Long]

Spaming the list with multiple inane "REMOVE" messages will not get you 
removed from the list. There is a link to the mail list interface at the 
bottom of every single email you receive from the list. If you are unable to 
figure out how to unsubscribe that way, then *ask* the list. Quit spaming the 
list.
