1. Another SMALL but important BUG:

Choosing pay per Day the caption for Number of Units field ''Days'' is OK. But this should change if user selects ''pay per impression'' to Impressions AND ''pay per clicks'' to Clicks.

Alternativly please write ''Number of Days/Impressions/Clicks'', but that would look quite unprofessional.

2. Is some kind of moderation/approval of banners by admin planned? Right now people could advertise anything they want... not that good
