Login woes

1. VU→“You need to login to vote”→login via facebook→page missing.
2. Logging out takes me to homepage. It should keep me to the page i’m currently browsing
3. Give Karma→“You need to login to give karma”→close dialog→Login→Page for giving karma opens. Since I closed the dialog box that asks me to give karma, it seems natural to be redirected to the topic I was viewing instead.
4. Maybe it’s just intuition but I’m automatically logged out more often than I’m at other forums.

These are very simple issues but repeatedly hamper the browsing experience. Please fix them on high priority.
