In some cases some of these sites do work. However, discussion of those sites on WiiChat isn't allowed and is considered advertising. If you would like to know more about those sites I suggest on doing a search on google. Please note that if you do happen to come across a site which may/may not be a scam please avoid from discussing it here on WiiChat. This includes posting links to the site in your signature and posting threads which relate to a discussion of one of those sites.
Note: Considering that this thread may lead to advertising and members posting referral links to sites mentioned above I've decided to close this thread. In the mean time I suggest on doing a quit google search if you wish to learn more.
