I am going to bump this topic because it was interesting.
Yeah, there are a ton of forums out there and it is neat to be around as many as possible. I personally partition my time as much as I can between Lyoko Freak (my most active area), Tech Links ( I pipe up every now and then but I mostly lurk and listen to all of the neat stuff they have and do.), other sites and cl related sites, and like ulrich stern to stay in touch with the masses of fans for cl I go to the offical forum ( where I lurk exclusively). I would honestly spend a lot more time at cl.com if I didn't have such a hard time reading half the posts that are on there (and yes I understand that many people don't either care or have trouble spelling, but I would at least love for people to use a spell check.) so lets see if I can give you guys a precentage rundown of my online time
LF- 50%
Techlinks-20%
CL.Com- 10%
other cl boards ( which i think is about two or three others) 10%
other sites- 10%
