OK, tomorrow AM is when these two things happen in my league.  I guess I took over a pretty decent team because in spite of my lack of knowledge we are on track to make the post-season right now, so I need to know how both of these things work.

1. Will the maximum roster size simply increase when I go to the "Edit Rosters" page?

2. If I promote a few guys for the stretch run and have a 30-man roster for these last couple of weeks, is there some additional option for specifying which of my players is on the 25-man roster for the post-season?  If so, where is this option?

3. If I have any minor league teams moving forward into the post-season, do I specify their post-season rosters as well?

4. I know this is a dumb one, but I'd like to see my minor league teams that are in the post-season do well there... is there some deadline for moving minor league players around in time for their post-seasons?

Thanks in advance for help!

I don't believe there is any limitations on the minor league rosters.. feel free to call up any players to any of those teams at any time

1.  It will show 25/40
2.  You will have to set your post-season roster.  Playoff Add/Playoff Remove will appear in 3rd column.
3.  No, just activate the players you want to play.
4.  No, you can move minor leaguers to your heart's content.   But you'll have to keep 20 minimum at all levels.
