hideAd is a Plugin for WordPress 2.x that allows the owner of the blog to embed advertisement but anyhow give the periodical visitors the posibility to hide these ads. The advantage is obvious: continous visitors uses an ads-free blog, once-visitors and those who came from a search-engine see the advertisements. Needless to say that not only advertisements but everything that can be built into templates can be hidden.
The principle of the plugin is quite simple: It plugges itself into the plugin-structure of WordPress and sets, if an visitor don’t want wo see advertisements, a cookie, that contains this information.
