What exactly is the differences between user,subscriber/roles, and members. I tried searching all over wordpress.org, forums, support and such and just ended up more confused. I have Jetpack plugin installed and am using MultiSite. I understand conceptually that MultiSite is like wordpress.com (i.e 1 installation multiple sites/blogs) but with JetPack (I know I may need to goto their website for better support *Sorry* just trying to give an example and more info on my installation) they have a feature that lets visitors subscribe with an email and receive emails of new posts to the site (per site in MultiSite) and those that use this feature dont show up under Dashboard>Users but instead in under Jetpack>Subscriptions. So my question, what is the benefits of having visitors create logins on the site (i.e 'Register')...1 I can think of is tracking and stats purposes vs. having members or Subscribers via JetPack which doesnt seemto have as great of stats info, esp. since the JetPack subscribers can read posts in email and never come to the site thus I have no stats on their possible usage, and also vs. the different roles available to 'Registered' visitors who login (admin,contributor,etc).
Sorry for the long post, but never found a complete understanding incl. pros/cons. Thanks so much.
