To be honest, your thread's a bit too general to move anywhere. All three of the subjects you mentioned could be video games, anime, maybe even trading card games. I can't move it to Other Entertainment -- it's the completely wrong forum for it.
If you have something more specific to talk about (like a certain game or the anime in general), make a thread in the right place. If it's for the TV show, it'd actually go to
Pokemon TV Show and Movies for Pokemon and
Japanese Entertainment for Yu-Gi-Oh and Digimon. Video games would go in
Other Games for Yu-Gi-Oh or Digimon, and for Pokemon, we have different forums for each generation. Check them out
here.
If you want a really broad discussion topic, another option you could do is make or join a fanclub. There's lots of different ones for
Pokemon, but in
Other Clubs, there's no Yu-Gi-Oh or Digimon club that I saw after searching. You can always make one? :) Make sure to read the rules there, though, found in the Mixed Community Groups forum I linked. :D
In short, there's really nowhere this fits since it's so broad, so I'm going to close this. Sorry if I was too confusing! @_@ Just send another PM and I'll try my hardest. :D
