We apologize for the instability of composr.app and appreciate your patience. We are working on the statistics addon and trying to find an optimal way to store and render data. Unfortunately, we have yet to find a solution that can handle the traffic (and therefore, tens of millions of statistical records) of composr.app. We're working hard on one.
I'm actually going to close this, and post a new zip in #977 -- it makes sense to deliver these together. So I would suggest using the zip from that issue, not this one. It'll be in the same git branch.
#976 - Allow custom email prefix/suffix
I am holding this issue open due to the need to merge into v10.
