We set up all of our member accounts manually. I did set up a dozen People Admins to spread the work out. We accomplished the set up of ~4800 accounts over 3-4 months.
It's do-able, but tedious.
Thanks for that idea.. I have to make member accounts like 5,000 more or less and is wondering how I'm going to do it alone and I have a lot of other works need to finish.
