I've seen the banner ads about now on dp for 'forumlinkbuilding' - their website sells forum spamming services which are not allowed in the buy/sell forum. So my question is: Are you allowed to link to sites in your sales thread if your website sells services that are not allowed in the dp sales forum? I mean if you made a sales thread offering a service that was within the rules but have a link in the bottom of the thread saying something like "more services on my website <link>" Or would that have to be in the signature? Cheers.
