I really need to figure out how to organize my members alphabetically by their last names in the member list! We need to be able to click on those letters at the top and have them sort by last names instead of usernames. I already figured out how to add just the last name custom field to the listing, but I still don't know how to make it alphabetized by that field. I thought I found the answer in the link below (post #11), but I tried it and had problems.

Can anyone
please help me? I need to get this done very soon!

I have a re-launch in a couple weeks and we're doing a test group tomorrow. I would really like to have this done by then!
