QFG Mailing List - a mailing list for discussing QFGV and the other games
Hero's Tale Inn Forum - my site's forum has a focus on tech support, hints, general game discussion, and anything else related to QFG.
FACS message board (official site) ~ if you are looking for hints, be prepared to be spoiled, because this board gives away a lot about the storyline of the game. The best way to get hints, i think, is to ask someone on icq or ask via the mailing list.
Halfwittenberg Door message board - Hans has his own board hereQFG5 Discussion Forum - a board at the qfgv news hotline site
QFGC Message Board - QFG center board
The Ultimate QFG Board - Bravenet's QFG board
