(adsbygoogle = window.adsbygoogle || []).push({}); NGU gets an average of 197 signing in for NGU a day. 197 times 365 is 71905. In an estimation 71905 will have joined NGU each year if every body keeps advertising. 496 times 71905 equals 97712.
(sorry for messy title) It's been 496 days that is equal to 97,712. NGU has 98,044 that's an extra 332 since this is an estimation when FourZerotwo mentioned NGU 100 immediately came the 232 were from the opening days of NGU. It keeps rising so best of luck!!!

[mod] We receive atleast 100 members a day, 250-1500 in the summer. NGU started on 05-11-2008, official opening. That's 495 days, or somewhere close, and 98,000 members. 98000/495= 197.97979797 per day.
