[Asterisk-Users] User events - a dumb question

[Asterisk]

Ok, this is probably stupid question of the week. I have

exten => 888,1,whatever
exten => 888,n,UserEvent(Event|Data)
exten => 888,n,Hangup

If I asterisk -r, when I dial the 888, I see Userevent appearing in the 
console.

However, if I telnet to the * manager using a name and password that has 
the "user" option, that telnet session sees everything but the user event.

What am I missing ?

manager.conf:

[event]
secret=event
read=system,user
write=call,command,agent
