How free members can get unlimited Tactics Trainer

Before I paid for a membership today I was using the Tactics Trainer and I was limited to 3 problems per day as a free member. After my 3 problems I was looking around the website at my options and how much they cost. As I was changing my settings/piece style and color I noticed the Tactics Trainer settings have an option where you can clear your Tactics Trainer history. I did that and I was allowed to do 3 new problems. I did it again and again. Basically allowing me to have a free Tactics Trainer but no records kept. I knew I was going to be a paying member but since I might have found a "bug" in the system I wanted to play with it.

Or maybe it isn't a "bug" and every free member knows about this.

Maybe it saw your username, thought you were a colleague and decided to make a professional courtesy.

If that's the case, I hope I get some Royalty checks in the mail.

thanks. noted :)
