What's the user

THE library user group is an alternative name for 'friends of the library'. 
          They are the groups in the borough of Camden and elsewhere that organise events in the libraries and campaign for various causes.
           I think the term 'user group' sounds stronger, but some libraries started using 'friends of...' so they stick with that.
           One group decided to change from 'user' to 'friends', but someone reminded them how difficult it is to change the name of a bank account, so they immediately changed their minds and stayed as they were.
