Blogoforum - Return to the post after signing in

Denis, you encouraged me to throw more suggestions. Here you go!

What happens:
- I browse the blogoforum, not signed-in. I don't care about being signed in at the moment.
- I find an interesting post, I want to reply.
- I realize I'm not signed in.
- I sign in: type my login, password, press the button.
- I find myself in my personal Blogoforum page, instead of the post I wanted to comment on.

I would be best if after signing in went back to the place where he/she was just before signing in.
