I'll clear this up; you are both correct.
You're both right!
Miner_man is looking at the Forum Stats and sombrerodude is looking at the Game Stats. According to the numbers on the Game Stats, it will be about 15.6 days until 30000.
You are correct in that the server system has around 29,400 members (according to the game statistics page) this is true. It is also true that we have over 30,000 members too though
. The information on the Game Statistics page does not include those members who registered before we added in the automated membership system and then didn't become a member afterwards. Whereas the information on the homepage and the Site stats does include these as members. Thus the two figures are different.
