Very basic newbie questions

I watched the intro video and read a bunch, but am still not clear about a few things.

1. Is omeka local software that resides and runs on your own computer?

2. Can you create completely separate web presentations for various purposes with no navigation between the presentations?

3. Can you publish web presentations to web servers of your choice?

1 & 3. It's server software, requiring Linux/Apache/PHP/MySql, which is pretty common on most web servers and hosting companies.

2. As separate installations of Omeka, yes. Or with easy customization of an individual site.

You might also want to try out a site on Omeka.net to try it out and see how it works.

Thanks very much.
