Hello,
There is a new group being formed in the UK re:IDOA - The international Donor Offspring Alliance. It is a group not focused on "support" as such but specifically on lobbying and advocacy.
Below is the link and is very worth while a look at current recommendations this group is going to put forward to parlament in the UK.
I'm hoping support and recognition will follow in and from Australia
