Possible, yes. I'm not going to do it though, since I don't want to reply on javascript.

Go through your Usergroup settings again.

mmm

where exactly please?:confused:

Global settings. Make sure that 2 is in the option where you choose which Usergroups the advertisements should display to.

perfect!
thanx a lot

Not quite, I just realised I read your question wrong. Sorry. You must already have 2 there, you need to add the Usergroup ID number for every other Usergroup you want to see adverts. :)

What would I have to enter in the CP to ensure I comply with Adsense TOS?

That I couldn't tell you, I don't actually use advertisements myself so I'm not au fait with Adsense's TOS. But I believe roughly speaking they require original "content" on a page displayed with advertisements. So search results, registration pages, redirection pages and so on where there is none would be a no-go.

Don't take my word for it though, be sure to look it up yourself.

Whose TOS? That's what the THIS_SCRIPT setting is for, so you can avoid violating advertisement provider's TOS by excluding certain page types. If there are other things you need to do to avoid violating a TOS that's up to you.
