Just a quick note that I've been struggling with my spam filter lately, as it seems to be grabbing more good comments than bad ones. I see regular posters trying to submit their comments several times over. I have neither "approve this user always" button nor "turn off spam filtering altogether" button, so I don't have a good solution to the problem yet.
In the meanwhile, if you're trying to submit a legit comment and you think it's being filtered, drop me a line and let me know so I can go fish it out. I get no notification that there's messages waiting my attention, either :(.
