Several times in the last couple of days I've logged in to post new threads or replies, spent maybe 5 mins composing them, hit "submit" and been taken to as page telling me I'm not logged in. The worst part is that my post disappears and cannot be retrieved - a completely frustrating waste of time.

What gives? How long does the site permit one to take composing a mail before logging-out and causing one to lose one's work? Never happened to me before the revamp.
