questions about replication

[bretch]

hello all,

I have a question on replication,

1. Do i have to redistribute replicated copies after some modifications on object in the database?

2. Does synchronization on replicated copies includes the modifications on forms, reports, queries, objects etc... from the master database?

3. Should changes or enhancements of the database necessarily be made on the master database?

my questions above are somewhat interrelated....
can you help me on this please.....

thanks
