I'm surprised a solution to this hasn't been posted before but I cannot 
spare the time to search for it.

Looking at the code for MM 2.0.8, the handling of 
DEFAULT_ADMIN_MEMBER_CHUNKSIZE in Defaults.py/mm_cfg.py and the associated 
setting of the MailList instance variable admin_member_chunksize is unlike 
other such instance variables; the variable is not presented for 
modification in the admin web GUI and doesn't appear in the output from 
config_list. You should be able to use $prefix/bin/withlist to set 
admin_member_chunksize. For example I did the following and it appeared to 
work OK:

1. created file called chunky.py containing:

def chunky(mlist, howmany):
     mlist.admin_member_chunksize = howmany

2. ran $prefix/bin/withlist to change members per page to 10 from 30 as 
follows and got results shown:

[barrett at mailman mailman]$ bin/withlist -l -r chunky rbtest 10
Loading list: rbtest (locked)
Importing chunky ...
Running chunky.chunky() ...
Unlocking (but not saving) list: rbtest

Hope this helps but be careful using withlist; you can make a mess of 
things quite easily I suspect.
