When ever we save universe it directly gets saved in local 
repository. If we want to access these universe from deski 
or webi then we will have to save these universe to central 
repritory by EXPORTING it,it will directly be saved in 
dafault location in central repository.

By exporting the universes and documents, we can save them 
to the repository. We can also publish them to the central 
repository.

if u are working in client system u must save ur iuniverse 
and files in server system repository.

the process..before exporting u should save the universe or 
document

file-->export-->report conversation tools..>ok

it is the real time senario...when ever u are working on ur 
personal system .server edition should be install...work 
with the repository
