Hi, I had problems importing dates in suggested european format - dd.mm.yy didn't seem to work. I think it was still treating them as US. I had to change my import file to be mm/dd/yy and it worked okay. Cheers.
Import function uses standard PHP functions to convert string to date. http://www.php.net/manual/en/datetime.formats.date.php If you open your CSV file in Excel, and get your dates recognized as dates, you can set cells format a date format recognized by aMember, and save CSV file back.
