Dang, John!  One mistake in nearly three years, and you guys have got me
paranoid.  Ya' know, just because you're paranoid doesn't mean "they're" _NOT_
out to get you ;-).  I signed back on to verify the information I _JUST_
checked.  Device descriptions and message queues are, as stated earlier by
Dave Shaw, created in QSYS.  OUTQ's are created in QUSRSYS.

Agreed here, but the only limitation is for OUTQ's...

No, no, no, no, no ;-).  I _by no means_ meant to imply that security
shouldn't be tightened down.  I am a _HUGE_ (no smart aleck comments about my
stature from those that I've met, please) supporter of security issues.  I
attend those marathon security BOFs at COMMON, and try to help make the /400
more secure when I can.  I agree with Steve Glanstein's position that security
level 50 should be used unless you're going to lose vendor support over it --
and that you should look at dropping vendors that would do so.

Agreed, and _this_ is what I meant to imply.  Be careful, use a "development
box" for testing if you can -- many of you have a Y2K box installed that would
be perfect.
