Jefferam,
No need to register...it is open to everyone. They have coffee and tea at the back of the room. You might check with your brokerage house to make sure you selected that you want to receive proxy materials for your SGR shares - that would be the voting papers and info packet. You should have received it by now unless you opted out.
The AGM is not only very informative, but it adds a lot to have personally met and interacted with Dale Ginn, Hugh Wynne and others from the company - people we hear about all the time, and now you have a chance to meet them in person.
Hope you will come.
