Two suggestions.
1) In order to try and get around Adblock, it would be good if, as well as being able to change Server Access Paths and the Delivery File Names (as we currently can), you could change the parameter names (e.g. 'bannerid').
2) The current email report going out to advertisers is *ugly* (sorry, but it is). Also, it is text only, so links come over as the full, unclickable URL (to which the link fails anyway). Some sort of customisable email report system would be nice, with HTML emails that can take logos.
