Very cool - registered a bit ago and taking another look around before sending that.

Two other things I noticed while going through that process and then poking around today:

The password length of 4-11 seems like an interesting choice - not necessarily a major thing, but given the overall level of security that is common and encouraged in the Bitcoin market, is that something that is easily changed to allow a longer password?

The graphs really look great and are a solid representation of data that otherwise isn't readily accessible on other charting sites.  Do you have something in mind for increasing the time scale of the graphs so that they can be viewed over a day/week/month/year or custom timeframe?

As a follow-up to that second point - the inclusion of a time-zone selector for individual's accounts would be awesome, to populate the graphs with.
