Where do I find documentation for the Import Member List feature? I can't seem to find it in guides. I am getting an error (6) when choosing my csv file and I am wondering if I have too many columns or something.

Maybe there are some discrepancies between the two forums, for example the forum where you exported the list has different style names, different usergroup names or whatever than the forum you try to import the list. Just a guess, had something similar when I tried to export a page database into a new created forum. 

I would recommend submitting a ticket.

This is happening on 3.4 beta 4. I assume I should not be submitting tickets for a beta program.

When we tell you to or suggest doing so, you should yes. In this case, I would recommend submitting a ticket.
