I just noticed that myself Andy (in fact on the same exact post made by Terry that you show) The adds seem to appear in the first post of every page in any given thread. If it's something the management here has started to help ends meet I don't have a problem with it, I was just concerned that it might be some kind of unwanted thing that might be hiding some kind of virus or something.
Its seems there is a glitch or something between registered members and guests. This is what you get when you don't log in. Notice it states that Registered users don't get ads ....but now we do!
Please check settings of your net browsers. It is possible that recent updating of them changed setting of pop up windows with advertisement. I don't have the problem and can't see any of these.
sorry about that guys....and thanks eric. I am getting ready to update the site and move over to a new server. So I have been getting some tweaks in.
I will have to introduce some ads, but nothing like that annoying in post ad. With the new server it costs a bit more $$. They will be much more subtle and not everywhere.
