I am using Xenforo 1.1 and aMember 4.1.9 with the latest Xenforo integration plugin. I have some users in my Xenforo database already, and I am importing users into aMember from another platform. Some members that are active in Xenforo are not also getting imported into aMember. What will happen when I run the database sync in aMember? Will it remove users in Xenforo who are not also in aMember? Or will it simply add any missing users to Xenforo that are in amember? I could use an answer asap. Thank you.
