If you sign up with adsense seperately (not through vBulletin) and generate adverts manually you can set up a thing called site authentication. Its possible you can also do this with the inbuilt adsense but we don't use that so I'm not sure.

Site authentication will let you provide adsense with a dummy login that their crawler will use to access member-only areas of your forum so it can retrieve keywords from those pages to display relevant adverts.

Its a bit fiddly getting it to work but in short you'll need to enter:

Protected Path: http:/ /www.mysite.com/forum
Authentication URL: http:/ /www.mysite.com/forum/login. php?do=login
Authentication Method: POST
Parameters:
vb_login_username = WHATEVER_USERNAME
do = login
vb_login_md5password = THE_MD5_HASH
vb_login_md5password_utf = THE_MD5_HASH

Change the stuff is red as appropriate.

For the last two bits, the stuff after the = is the MD5 hash code of the password for the username you have setup. Finding that out is fairly easy if you're internet savvy but could be quite challenging if you aren't as you'll need a firefox plugin. Google it for more info.

• Don't give it the password for an admininstrator account! Thats just asking for trouble. Just create a fake registered member.
• Give it a simple/non-obvious username like 'Apple' or something.
