No idea how tough it would be but I think a great addition to this would to be able to export an event's attending roster to a CSV or Excel file. In a perfect world the users profile info to be exported could be ACP selectable. So you could get an output something like:
Code:
RMS-Chef,whatever@hotmail.com,http://userswebpage.com
JohnDoe,jd@yahoo.com,http://yahoo.com
