Bicycle NSW has developed a Forum for Bike Groups affiliated with it. They hope it will allow discussion of common problems and interests. If you want to sign up please email us on firstname.lastname@example.org and we will send you the code for the sign up process. Once signed up you will create your own password to log in with.
The Forum is here. http://forum.bicyclensw.org.au
Only early days, it needs time to build up contributors and topics. So get thinking!
