If you desire genuine information about Old Believers, Reditt and Byzcath are probably not going to be as reliable as websites maintained by actual Old Believers themselves. Be careful on those other sites. Something else to remember is that not all Old Believers are the same. There are now many sects and not all follow the same traditions.
