Personnally... only Code Geass has fallen on such category. The other series on fuego haven't sparked my interest.

I still wish they would just have sent all the geass threads to a 'old fuego' sub-forum instead of merging, but I guess policies are policies.

Geass R2 alone had 1700+ replies.

Soul Eater and Tales of the Abbys together have 500 until now. To be fair, Abbys is new, but Soul Eater has been around for a while already (30 episodes)
