Do you miss something on BrainKing.com and would you like to see it here? Post your request into this board! If there is a more specific board for the request, (i.e. game rule changes etc) then it should be posted and discussed on that specific board.
For the case of the merging or reorganisation of the chess dbs I would suggest the following disposition:
1. standard chess
2. random chess (includes all random variants like chess960,corner,fortress)
3. other chessvariants with the 8x8 board
4. 10x8 chess (includes Janus,Gothic,perhaps Capabalnca randomchess)
