Ouch .. I got several requests about this off list (that and how we use
Gmail for collaboration and documentation) .. I'll do that and work on a
workshop for after school on a Monday during November and have the techs on
hand for a show and tell.
Regards Roland

> Hey Roland,
> just noticed you said you'd virtualized. We are looking at that as an

> otherwise, it works for you guys in terms of speed, time savings, system
> management etc.
> I am currently doing an infrastructure review here and would appreciate
> your experience with that setup.
>
> Sent a copy to our techie here for his input too. He will be implementing

> We are not locking the junior kids out of rooms or away from the
