Audit User Administration Activity

Any tips/tricks on how to audit user administration activity (password resets, account inactiviations/activations, account lock/unlock, etc.)?
There's nothing built into the FBA Pack right now. It's a good idea though, so i've raised an issue so we can look at adding it to a future version of the FBA Pack:

In the meantime, you can query the membership database for last login date, lockout date and password change date.

You could also potentially modify the membership database stored procedures to store this audit info in a separate table.
