Background Syncronization

Hello All,

I have two replicas of my master database that I want to replicate.  The 
data will only be added and edited in the master file.  The other two 
replicas will only view and print.  I would like the replication to be 
automatic or at least give the main database a menu option to syncronize. 
I 
can add the menu option but the user is always prompted to choose the file
to 
syncronize with.  The option to syncronize with all replicas in the 
background is not available.  Any suggestions?

Thanks,

Rob
