While on Tintin, I came across this fan site of Tintin www.tintinologist.org - the Cult of Tintin. The site claims to be the oldest and largest English Fan site of Tintin. Tintinologist has some pretty interesting resources like Tintin Books guide, Tintin characters guide, Tintin shop directory. There is even a section on Captain Haddock's curses! There are a lot of Tintin news and articles on the Boy adventurer. The forums at the site are pretty active and responses are fast and furious. Needless to say there is a raging discussion on now on Tintin being or not being gay!
If you are a Tintin fan (like me), this site is a must visit.
