Hey Everybody—
Posted this to the list a couple of months ago, but didn’t get any responses.
Is there a better place to ask this question about quota & namespace
configuration? Seems like a lot of the discussion here is a little
deeper/lower-level than my configuration question, like debugging and
development…
Thx,
Fred
