I'm sorry to admit, but trying to sign-up active members for my website has never been a priority for me.
I don't even know where to start.
I started just looking at the backend of my wordpress installation and other than the standard "Blog Subscriptions" that comes with Jetpack I don't see anything.
What are some decent Subscriber/User management tools I can use? I have lot's of Image Galleries so I'd like to keep my subscribers informed of new images as well as new posts. Security is also a big plus.
