Subscriptions graph doesn't make sense
On the EE site, Moderator Tools > Reports > Users yields the following graph:
This can't be right, because it shows users joining before 7 June, the day the site was launched. It's also not clear what the real Y axis units are, since absolute numbers of signups is meaningless without a time interval, like signups/fortnight or something.
These are low priority issues since this graph isn't critical for anything. I noticed it, so I'm mentioning it just to get it on a list to address eventually.
