I sold out my NXS on friday. probably just broke even. If anybody lives in Melbourne and has some free time here's a way to get contact information for the top shareholders:
Any person is able to inspect the register on hard copy. If the person and the company agree the information can be accessed by computer. The information that can be inspected includes the members name and address, the date on which the members name was entered in the register, the date of which every allotment of shares takes place, the class of shares and the amount paid on the shares, but not access to share certificate numbers.
This denial of access to share certificate numbers in all cases is a significant protection against fraud. The SCH Business Rules also provide for confidentiality of the HIN/SRN.
Access must be provided to the public; members may inspect without charge, non-members may be charged a prescribed fee of $5.00 for each inspection if the register is kept otherwise than on a computer, but if it is kept on a computer then a "reasonable amount" is determinable by the company or its agent so long as it does not exceed the marginal costs of providing an inspection. Most companies do not charge a fee for register inspections.
