Richard,
Thanks for the answer.
So what is the proper way of managing user quota on database (apart from
having separate table for each)?

Isn't that asking for spam (and I know the answer to that)? Why would it
matter for someone to answer my post based on my email address, if the
discussion is going over the groups? One might just as well use:
fake_user@gmail.com. At least I'm forthcoming by making it obvious that my
email address is not real. Just a thought.
