Playing only unrated games after some time for non-paying members is the most used restricton on other chessservers..

..and they mostly must have the opinion to get more paying members with this mode.

But how, assuming it's factual, does this translate in net revenue production? What chess playing pawn is going to be compelled to buy a membership here because of the simple prospect of losing his rating status? Rather, it seems more likely he'd just go find another of the hundreds of free chess sites already on the internet.

Ughaibu : the remarkable feature of this site is especially,that it is often down and it needs more money for a new server.
Pioneer: I am sure some pawns will leave, but I am sure too that some others will buy a small membership and than the site has more money to buy a new server and we,the paying members have a site with a better technique.
Other ideas are welcome too, I think.
