GLBSE's Shares Issued is more like Shares Issuable. If dividends have been paid, maybe you can use the Shares Paid as the share count instead?
Regular stock exchanges (NYSE, NASDAQ, etc) call that number "Shares Authorized" and it's larger than or equal to "Shares Issued and Outstanding"
The "Issued and Outstanding" shares get the dividend, that's why people are saying to use that number.
GLBSE should really show both and label them with the standard nomenclature.
