Access Spilt database changing forms & queries

I've probably made a mistake here but I'm new to split databases.  I split it a couple of weeks ago & all is running well.  Since the split I've written a few queries in my version of the front end, & I think one other user has written a query in his front end.  

From what I've been reading this means we now have two different front ends & if I now make form changes to my version of the front end that I want to copy across to everyone else, this means the other user will lose his queries.  

I assume I can backup his modified front end & then copy & paste his queries into the new master version.

I think the normal solution is to provide other users with a compiled version so they can't make changes.  If I don't want to do that, I just have to declare a rule that anyone who wants to write a query has to do so in my 'master' version (in general I like my small number of users to be able to write their own queries if they know how, less work for me & allows them freedom of enquiry).

So there's no real question here other than - is what I've said above correct?
