Seems like a bug to me. Looking in "User List" then click on any letter, SOMETIMES it does NOT show your member list of that letter. A useful moderation? Clicking on a User name to see their account: Please DISPLAY that user's NAME. A SERIOUS mod: Allow us to IMPORT from a spreadsheet or database or txt file MULTIPLE USERS, PASSWORD, PRODUCT paid for, Subscritions and the start and expire DATES Many FREE programs already provide that!
Could you send me URL which shows a bug and corresponding login info? Have a look at aMember CP -> Import
