Thanks for the warning! This is definitely not a production site. Just a small site for a few friends. I only forwarded up to the latest commit to see if that would fix the issue, but it does not.

Whenever I try to click the check mark for a user on the registration queue, I get a little error popup in the lower left that says "Error write EPIPE".

After that, if I try to approve the user again, it simply says "Error email taken". However, the user seems to actually be created successfully, and I can assign them to groups, etc. The email that would normally be sent to the user that their registration was successful won't be sent, though.

I'm not seeing anything in the server log about this error, unfortunately. Seems like a redis error but the redis logs also show nothing that is helpful (maybe the verbosity level isn't high enough.) If I can provide any other helpful information please let me know.

I'm at commit 0516418 on the master branch (happy to make this a github issue if that's easier.)

In any case, many thanks for these awesome forums. They are really great!
