Log in redirects to the home page even if log in is on a specific page on the site. User comments below:

I wanted to point out a small niggle I have with (the otherwise
excellent!) Oxford Talks: departments increasingly share information
about their talks by simply sending me the Oxford Talks link so I can
add it to my collection. If I click on the link I first need to log into
Oxford Talks before adding the talk; however, once you log in you are
taken not to the talk itself but to the Oxford Talks home page, thus
losing the link. You then have to go back to the original email to find
the link again. It's a small thing, obviously, but it makes the process
a little bit more time-consuming and cumbersome. Is there any chance of
this being addressed? I don't think it's the case with most sites where
you use Single Sign-On to log in.
