powderday has an email list serve on google groups. We encourage you to visit the group at http://groups.google.com/group/powderday and post any questions you have. You can also search the email archives there.
You can also directly email the group at [codename] AT googlegroups.com. For the benefit of future archive readers, if you could please include a descriptive subject line of the issue you’re having, that would very helpful.
If a run crashes, it can oftentimes be very useful to post your parameters files as well as include which hash you’re working off of. You can recover the hash by typing:
>git rev-parse HEAD
And similarly, if you want a neat way to create a link out of your parameters files, you can type:
>yt pastebin parameters_master.py >yt pastebin parmaeters_model.py
and two separate links will be created with the parameters files.
