Is this usual? I am assuming this search bot has complete access to my forum as a registered user, as this pic demonstrates
the bot can go anywhere a guest would go, if the forum is closed for guests than its closed for bots actually it depends what forum software you use which one are you using?
I'm using phpbb3 beta, it's been pretty good so far. I don't really care whether the yahoo bot has registered status on my forum, as I want to be indexed. Although I am surprised that I am being indexed when my forum was just setup yesterday. As well as me just changing nameservers on my domain yesterday
