I'm following this thread: http://www.ubercart.org/forum/support/2493/export_catalog_db and I wont to do the Lyle's procedure:
Pick one site to be the master catalog. This will be the one you make the changes on. On that site's Repeater settings, list the domains of each of your other sites as slaves. On each of those sites, list the first site as the master. (Basically, leave off the "http://" part of the URL.) Now, when you edit a product, there will be a check box labeled "Export to other sites". If it is checked when you submit the changes it sends a message to those other sites with the new product values. Since it uses the importer's XML functions, make sure the Importer settings are set to overwrite existing products. This makes revisions so you can always undo the changes if you need to.
Where I can find the two modules(Importer+Repeate)? Here or in Drupal/Project? Can you link me the right place?
PS Sorry for my poor english
