I've already checked a lot of posts regarding this topic, but could not find the exact answer for that.
I would like to have 3 different sites with 3 different themes under 3 different domain names (domain1.com, domain2.com, domain3.com)
the only common would be the comments created by the visitors of the site.
do I need the multisite solution, or only multiple installs of wordpress to different folders on the server?
(also would be fine if I could use only 1 database, but I think also with separate installs I could do that as using an other prefix for table names in the database.)
