This code is a specific offer of help. It is a generic offer. It is up to the listener to indicate the sort of help that would be most useful to further the project. It is a clear signal of willingness to help.
Help is being offered. Help does not have to be asked for. It may be that the only help needed is that someone should show interest in the project.

Although code 17/12 is a clear offer of help, it could also be used as a request for help: 'It would be nice if we had a 17/12 here.'
