from a share point portal website, how can i tell what version of share point is running?

that is to say if i am browsing around on share point where can i get to a details page 开发者_开发知识库to tell me what version of share point it is?

Provided you're running 2007 and can select "Site Settings" (or "Modify All Site Settings"), it's right there on the newly-opened page to the right of "Version". From there, a pretty up-to-date mapping of version to SP/CU install can be found here.
