CS - any mudcatters who want to use the site for gratuitous self-publication have never had problems doing so.
Some of it is up-front - SHAMELESS SELF PROMOTION THREAD...
Others just use every posting they make as an advert for themself - Dick Miles is a current master of the technique.
Others on the forum welcome the security of relative obscurity, and the fact that we can tell people where we will be without also advertising to burglars, the fact that our home may be unoccupied on a specific date.
Quack!
