Advice needed for a "Membership plugin"

Hi Everyone,

I am new to WordPress and have just used ServerPress to install WordPress on my machine. I would like to create a website that holds Membership information (eg. Name, address, and points accumulated). There are so many Plugins (which is a good thing) but I would like help by way of some suggestions with which ones to try out without trying them all ??

Any advice would be helpful. I am already impressed with the default install and would like to take it to the next level.

Thank you in advance!
