On August 4th we announced that we had 10,000 registered users.  After some internal checks we now realise this was wrong.

The reason for the discrepancy was a number of spam accounts.  We became aware of these about 6 weeks ago (and introduced a CAPTCHA system to prevent future spam accounts) and have since been tracking down these accounts.  We now feel we have a pretty accurate figure for actual accounts and as of now, we have 9,873 registered users.
