[EEG] Fwd: open eeg/ocz nia "success"

This isn't that kind of list, Josh.  List noise is good.

And if it's on the list it's in the archives for 2 months later after
we forget about it and revisit it.  So post away.

That said, meeting is also good.  Traditionally it's been Sunday
afternoon, but we haven't been meeting for a few months.  I can put it
back on the calendar for this week if people like that time.
