I am wondering. Several members here have their own website. It might be interesting for them to advertise for AO by displaying a banner. Something like the text: "Member of" followed with the AO logo. And then of course if a user clicks on it, they will be redirected to this place.
Of course this would mean that AO would have to provide the banners that members can put on their sites. That is, if AO even agrees with this. But it seems an interesting idea.
