If anyone is interested we are discussing designing an utility program to find modules(both NWN1 & NWN2) here:
Single Player Lists of ModulesIt will feature tag system.
If you have anything to add, or a tag you would wish to see: join the discussion
Just thought it might interest NWN1 community as well, since its posted on NWN2 boards, that we NWN1 folks don't frequent.
