卷心菜 has suggested to include 新加坡棋手大全 in his proposed wedsite.
In general, we should have the complete lists of SIXGA 象棋大师 and 甲级棋士 from the various SIXGA reports or pulications. For 乙级棋士, the missing parts are those earlier years, i.e. 1987 to 2001, some efforts are needed in these areas as for the compilation of 2002 to 2008 List.
As for 无级高手, not a good way to maintain it before the introduction of few more lower grades for the players.
