One of my event managers has just asked if we can get the Last Name as a separate export field. The export is really helpful, but they have to do a lot of extra steps to sort by last name instead of first name. (It's sorted by last name while online, but if you pull the data out and do anything with it, you can't get it back to last name sort.)
We've just shipped an enhancement that separates out the name field into all applicable names, including Title, First Name, Middle Name, Last Name, Suffix, and Class Year (if you have the Alumni module) within the export. This will allow you to slice/dice/sort in the Export file as needed.
Take a look and let us know what you think!
Last name should ALWAYS be an option on EVERYTHING!
