Hi Chris,
I think a calendar of events (what day Easter occurs on this year for example) would be very useful for Webcards.
Just a list of the upcoming holidays and their dates that could be displayed in a sidebar or header so that users would know exactly which day the holiday falls on and when they would need to send their card using advance send for it to arrive on the correct day. Also if you click on the upcoming holiday it could link to that particular category if it existed (Christmas links to Christmas).
The software I sent you had this implemented if you want more info or ideas.
Thanks,
Brad
