HEAD
- Changes to: &create_account() third arg: $lonhost eliminated (not used).
- now returns third item - $uhome (lonHostID of new user's home server).
- Changes to calls to &start_session() - fourth arg is now $uhome
(lonHostID of new user's home server) instead of lonHostID of server
hosting session.
- Changes to calls to &Apache::lonauth::success() pass $uhome as fourth arg
instead of $lonhost.
