Hello, fravia+, I have found your site quite nice, just the sort of things i am interested in, wonderful to poke around at. I am quite flattered by your link to me, I have not really done so much in the fields of bots, anti-ads, but i'm flattered nonetheless :) I have only a small contribution for your site, for the obscure.htm page, some javascript that does the conversions nicely, ie and opera-compliant. I use it all the time, maybe someone else would like it too... -thanx,
