Romance Writers of Australia Conference 1997/Signature Bear /Opps now there are 28

Do you recognise this signature bear?

He's been sitting on my desk since the day I won him in 1997, in Sydney. Although I left RWA for quite a few years he's always remained in my office. He has 27 signatures.

But my problem is I only recognise some of the names. (not because they are blurry, because I can't understand the signature) :) If anyone can help I'd be most thankful. :) Perhaps someone that has signed the bear will know of the other names, and even if you haven't perhaps you may know if you attended the conference in 1997. I've put a question mark next to the names I can't read correctly.

 Thank you if you can help. :) 

Thank you. Kerri Lane has been more than helpful in providing the correct names etc. I have only two left so I will post up a photograph and see if someone can't recognise their signatures.
Thanks everyone. :)

Here's one of the signatures we haven't recognised as yet.

The other is just, Siane. Written very clearly.

Thank you. :)
