"MySQL-Front will automatically create a primary key named Id, but Rails prefers to call it id (all lowercase). I'll explain more later, but for now just change it." errr maybe i missed the explaination but if i wanted to use a more meaningful name than id or anything other than id, can I? so far everything i've tried produces errors

  its only logical that you want to adress the 25th reply (altogether the 1003rd reply) to forum post #64 by the multi-column integer id 64,25 and not 64,1003.
  url-naming is an important part of the user-interface.
