I am not even able to pull up matches currently. My father and mother each have over 4000 family finder matches. I work on a family at a time (currently trying to sort out the Jennens/Jennings family who had several children marry into the Maupin family) and I can not even pull up matches.
I will probably go to Geni.com who does attach both Y and MT to the direct lines making it easier to follow the line for potential matches. You can also lock a person's profile to prevent unapproved matches.
