I tried researching into this on google for a while, but I'm stuck.
Basically what I'm trying to do is this: I have a "big" main website. Then, on the same drupal installation I want to have a "mini" site that will have a completely different theme, and only one page (but the page will have multiple editable content). I also will have another site that will have a completely different theme, completely different navigation, and multiple pages. Final piece that has me puzzled is that this will be on a subfolder basis. By that I mean / will have the main site, /sitea will have the single page site, and /siteb will have the multipage site.
Any suggestions on how to handle this?
