Just try the noprocrast options in your profile. I have it set so I can basically browse for a bit in the AM, maybe do a comment and then I am locked out until the evening.
It's a useful feature for those of us working on discipline + distractibility issues.
I tried it several times, but I am usually a slow typist and English is not my native language, so I sometimes think twice about how to formulate a sentence. Sometimes when I wrote a posting, I ended up hitting the timeout, just when I was about to post. This is the only reason I turned 'noprocrast' off again, otherwise it is a super useful feature!
