make sure in your profile, in the sig section, that "bbcode" is set to "on"?
Anyway, I don't see a need for removing that 1 minute time limit. I'm not a big poster.
But I think the minute delay on editing posts should be removed. I often make small mistakes which I have to edit straight away, as to not make myself look stupid.
Also I was beggining to get worried, when BH wasn't loading for the past few days. I see everyone has been hiding out here though.
