Like the way champion chess tournaments are recorded.

Thanks for the suggestions you've provided recently in the various threads here in the forum. :) Right now the Go Pro is (primarily) for people who want access to additional educational content (teachers who want to assign activities, create new content for their students, etc.). Plus, of course, there's the added plus of getting rid of ads.

At some point we might expand the purpose of Pro Membership as you've suggested, but in a way we've backed ourselves into a corner. Some of the more obvious ways of enticing people to get a pro membership involve letting them show up in high score lists, as well as calculating their player ratings (this is how it works on Quote Puzzler - you must be a subscriber to appear in high score lists). HOWEVER, we're already providing these features FREE at The Problem Site, so we'd end up having to take away something we've been offering for free in order to have really good enticement for people to spend the $4.95. And no one is going to appreciate that very much.

Speaking of Quote Puzzler, the very faithful subscribers over there have been waiting very patiently for the new and updated version of QP (which I've been promising them for several years!) and they've patiently waited while we detoured from that project to redesign this site. But now, we feel pretty strongly that meeting the needs of our existing QP subscribers needs to take priority over spending much time adding new features to TPS for the purpose of enticing new subscribers.

In other words - adding more features for Pro Membership at TPS may happen, but it's going to have to be down the road.
