The xoopsmembers you refer to used to be part of the core modules, and came packed with xoops, but then the devs decided to have no core modules any more, so it got debunked and retired.
I've not tried the module mentioned above, but will probably be looking at it myself soon, as xoopsmembers becomes uncompatible with future versions.
Kind Regards.
