I have to build a number of different sites and there are certain extensions that I routinely add. Is there any way to script the loading of 5 or 6 additional extensions?
But if you deploy the same template with the same extensions, you can create one install, install the extensions, then use JoomlaPack to make a copy of the site.
JoomlaPack will create an installer much like the Rocket Launcher, so when you run it everything will be installed.
