We are launching a site offering market analysis and research for healthcare industry professionals. We expect to offer both long-form publications on niche topics and ongoing short-form items of strategic interest.
As every membership site is unique in its needs & requirements, it's a hard question to answer with one plugin. I would start with Paid Memberships Pro (which is free) and consider alternatives based on your site's needs.
MemberPress is the easiest to use but its not free and has its limitations. But 'Paid Member Subscriptions' is a nice little plug in and you can start with a free trial to see if you like it and play with the features. Personally I think Wild Apricot is the best option, its cost effective and has most of the feature you will ever need. Its not a plug in though, its a stand alone butttt it incorporates very nicely with word press. Hope this helps.
Jetpack has over four-million active installs, but many WordPress users still do not understand what it does or how they can use it to improve their website. Think of Jetpack as the ultimate toolkit for your WordPress website. Because WordPress takes some of the load from your server, it will help your site run smoothly despite the extra features.
