i highly doubt it is a bug, could have easily been web crawlers though.
we have been getting at least 800 unique visits everyday since the first week the website was launched. usually it hovers around 1000 visits a day. again, the forums only show people that are actively in the forum .. it doesnt include people on other parts of the website, I need to look at integrating it somehow.
Kind of off topic, but take a look at what little bit of exposure we got on digg did for the stats .. lol
The visits basically doubled in 1 day, and we didn't even get promoted
