Google bot at forums?zomg?!

So i was wondering what this is?

There's been a Yahoo one a few times too, no idea what it's for, though... Prolly just adding us to the search thingy

I've seen em both as well. Don't think they make that much of a diffrence though

ya saw that once or twice to
even the yahoo thingy
and another one but cant remember witch one :/
