Ahh, if events run asynchronously, I think I will need something

It's a personal "dashboard" view.
Does something new (e.g., a list of registered "user management
observers") have to be implemented to do this?
We did this in Sakai by adding a UserPostProcessor [1] bound into
modified the user management servlets [2], on the assumption that we
were going to force all user creation to happen through REST or put
the hooks in. We found that async observations didnt work for use
(because they were async) and attaching to the internal Jackrabbit
sync events was just bad as it meant mods inside the server bundle.
Happy to clean up the approach and push to Sling, or you could grab
the bundle as is and repackage your launchpad.

go here, or should I extend
the 'Create User' servlet?
I don't know the usermanagement code well, but if your operations can
be asynchronous, the simplest thing would be to register a listener
for parts of the repository that the usermanagement modifies, and act
according to events received.
Can anyone provide some online references for doing this kind of
thing?
The thumbnail generator of the espblog sample [1] works like that.
