There are several places where we assume the [Community User's][1] creation date is when the site was created - one of those places is on the /users list page for the "all" filters.

For whatever reason*, Community's creation date was incorrect, having a value of `2010-11-10`, instead of `2009-09-28`, or when [Anton's user][2] was created.  This would result in over a year of your votes not being aggregated.

I've updated Community to have the proper date, so everything should be fixed.

<sub>* I think it's because the old SE1.0 codebase didn't use this date for anything, so it wasn't imperative for it to be correct.</sub>
