[SM-USERS] Service level howto

[Patrick D. <li...@we...>]

Guys, I have a challenging question (or at least, I think it is),
Is it possible to define a service level, or something like a 
subscription level?
What I mean is that accepting people subscribing to a free mail service 
should differ from a paying subscriber. A payed mailbox could have more 
plugins, more boxspace, larger attachments, etc. Is there a flag that I 
could set to make a difference in the options package one should have 
access to? Must be that someone has thought of this before, so if there 
is a plugin or a script, please let me know
Thanks
