Fantastic, wonderful plugin. I have over 50,000 users but only 50 contributors. Unfortunately the plugin isn't limiting the selections nor caching them. So if I tell the plugin to select only 4 authors maximum and each must have at least 5 posts, it's not being efficient. Instead it takes over a full minute to load pages with this plugin on. Other than this serious problem with the query and the return, it's exactly what I wanted... Others seem to report success but not here.
