I was looking for a way to download my membership into a CSV file. This appallowed me to get exactly what I wanted with a fine grained, SQL approach. I have done the same thing in DotNetNuke and found it to be excruciatingly painful to do. With ArtAdminer and Joomla this became a cakewalk. The hardest part was finding the App since the name is nowhere near what I was expecting. Fivestars Plus for the author(s).
