What about using just a flag to mark that category/subcategory is available for the game? (In fact, I still don't believe flags are useful here, I doubt we will ever have training database with >10K games. -- Michal Rudolf ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
