Multi-site installation and one theme: how to know on which multisite user is? I have Drupal multisite, where I have three different sites. THey all use same theme. Now I would need to do small changes to templates that only visible on some sites. How can I tell on template level that what site is used.

For example on site 1's front page I would like to have:

Some content

But then on site 2's front page I dont want that div to be showed at all. Can I achive this somehow? Is theere "native" way to find out thie right site inside template, maybe in template.php?

Thanks.
i would suggest doing multiple themes, one per site/group of sites - where they all have a common theme as parent.

that way you can overwrite specific elements on individual sites without having to worry about adding all the logic to check what site your currently rendering content for.
