Membership 2 Pro and importing users

I can't find any documentation about the user importer feature. I was briefly experimenting with the previous version when I got the overhaul notice. What I need out of a membership plugin is the following:

1) Ability to import members who belong to a brick-and-mortar club
2) each member might have had their membership start on different dates, so they need to expire on the date of start, and I have to import that information
3) once a member exists, i want them to be able to edit and maintain an online profile within the site on the front end

can you help me? :smiley:
