Hi Sorin,
Your first impression is right ... almost all first impressions are always right

about adjusting the cron file ... that means this option goes for everbody.
it would be nicer if a bidder could choose what he wants.
Because some bidders live near borders of two states
for example
i want to recieve new entries mails from
category A - state a and c
category B - state d
category C - all states
I think to achieve this the categories template + database does need a modification as well
This would be a great plus for the service abbility from the component.
