I have a WordPress situation where I need to register premium users, collect basic information Name, number, etc, provide a password. Was originally thinking of keeping all within WP by using S2Member or similar, but I’ve never worked with an installation with quite so many users and am concerned about it handling the load. So my questions are:
1)Anyone know of WordPress can handle this load?
2)Any recommendation on 3rd party paid user management solutions that I could integrate into WordPress with a plugin or API?
