It should be possible -- and this would be great -- to be able to return to
the page you were on after logging in. (With the URL adjusted to HTTPS if
it was HTTP to begin with; especially as, otherwise, the site would log you
instantly back out on hitting a non-secure page).

Most sites now offer this, it's a standard feature now on the Web and
should be part of SourceForge also.

I am not sure if this applies anywhere to SF, but PmWiki is smart enough
that if your session closed that if you try to submit or preview changes to
a page, after the log-in page your changes are submitted or previewed. That
is, they're persisted across the successive POSTs so that you don't lose
anything.

I don't know if SF has pages where this applies (pages where have to be
logged in to perform an action, but it would be nice for example when
accidentally submitting a bug/RFE/reply without being logging in first) but
since it's cool, I thought I'd point it out.
