Fretta Questions

I have a few noobish questions involving fretta-
Q1: How do you make teams and/or classes randomized on who joins, kinda like TTT?
Q2: How do you set the maximum in a Team without autoteam balance, so one team might have a maximum of 3 and the other is limitless? same with classes.

if you answer Q1 and Q2… :flashfap:

-There was a Q3 but i threw it out.
please answer these
