Just a quick note now that our experiments have been underway for a month.
 Our study has been running smoothly so far, and we expect to eventually
have an interesting report on it.

If possible, can someone from Hurricane Electric please contact us off list?
 We have a quick question about our study.

Thanks!
Ethan and Valas (at cs.washington.edu and gatech.edu, respectively)
