CyndiM ~ maybe the ad being on the last post is the result of the modification that Paul said he would ask for. Because when it first started happening, it was on more than just the last post ~ they seemed to be randomly on several posts through out a thread.
It seems now to be on the last post of each page of a thread. That is tolerable ~ better than how it started out. Thank you Paul.
flower123 ~ I agree with what you said: if they have to use ads to pay for the site then I understand. Because I cannot afford to pay. I am grateful to have this community. Even if there have to be ads. AND I really like VBulletin. Its so easy to use.

Thanks for your reply. Have a wonderful day/weekend.
