Yes it appears we are soon going to have to CLOSE open membership to lottodds. The system is getting to the point where many will be able to pull in easy wins and huge prizes. IF too many members grab too much money from where many of us are playing, it could ruin things for us.
THUS, any existing members will continue to be members once OPEN membership is closed. Any NEW registrations would need to be referred by another member and subject to APPROVAL.
