Pre-sales question - sharing Kunena

[cmerx]

I have an existing Joomla 2.5 site with Kunena forum. I'd like to have a second Joomla 2.5 site at a different domain. The second site should include the same Kunena forum. No other content but the forum should be shared between both of the sites. Is this possible?

Also, can I get a copy of the user manual?

Yes, that's possible.
Second domain should parked on top of main site, so both sites will use same files.
Second site will use own database, but Kunena (and Users - also required) will be loaded from main site, so forum and users data will be always same.
