You might be aware of this already, but it is a request that would be highly appreciated by myself and I think by the rest of the community as well.
On my forums, I have specific forums which are not accessible for guests and also not for the google search crawler, because I prefer this forums not to be searchable through google.
However, it would be great if we could set separate access (f.i. as a separate user group) for the AdSense crawler, because irrespective of whether you can google these private forums, I want the ads on these forums to be as relevant as possible. The login feature of the adsense crawler doesn't work with IPB, as far as I know.
Please IPS, could you include code that recognizes the AdSense crawler and assign it to a specific user group? Thanks!
