Although the forum itself is advert-free, I do have some sponsored advertising on the main site. This is making a significant contribution to the hosting costs of this, um, "rather large" site. There are no flashing banners or other annoying gizmos - at the moment all are non-obtrusive text entries.
Some users of the site are a bit puzzled by some of them - they may appear curiously worded. These are designed to be read by search engines, to boost the search engine results for site referred to by the advert.
Please do not worry about these - there is nothing suspect and the site has not been infiltrated. I do "vet" all applications for advertising and decline many that are unsuitable or inappropriate. Unless you have a particular interest in the subject matter, there is no need to click on the links (we are not being paid "per click-through") so please just ignore what doesn't interest you.
