I am using amr-user-plus with my WP site and using S2member. I have read your blog post about using amr-user-plus with S2member here:
I am having very good success with generating lists and filtering them based on added custom fields. I have read other posts relating to using the S2member Custom Capabilities (ccap's). Have you had any luck figuring out how to use ccap's to filter a list using amr-list-plus?
