A great feature to add would be the ability to modify registration after it is submitted. I just ran an event that offered a number of optional items to purchase, and people contacted me after registering, wanting to modify the number of optional items, and I had to unregister and re-register them. I understand the difficulties associated with giving every event registration a login ID to come back and modify registration, and I'm not even asking for that - I'm just asking for administrative privileges to modify the number of optional items purchased. Otherwise, this is a really great product at a great price. Thanks!
