Hiya Eagle Eye. You're right. UBB Forum Software, too. (Which stood for: Ultimate Bulletin Board) also had this "delay" feature.

I remember UBB from the late 90's. Before forum software had an sql database, they just used cgi/perl scripts and flat html files for storage.

Sadly, there is now a whole industry which promises clients top spots in the search results. Which they think can be achieved by repetition of links - even on pages where the links do not fit the context. But the main search engines are catching on and can actually punish such contrived "link popularity".
