List of possible actions for registration WordPressMU

Hello everyone

This is my first post because yesterday I join so nice to meet you!

I'll have a question about the inclusion WordPressMU.

I would like a list of do_action possible so that I can,
Once the user has registered, get the id, the login and password chosen in order to perform actions with.

Not finding what do_action use, I added in the core of wpmu .... which is not good: x
Before putting it into production I'd like to do a clean way to restore the original files!

Thank you:slight_smile:
