1 Sportsworld Sportsworld i don't see being too popular becides that can be discussed in the lounge since its off-topic.
2 Foodworld same with sportsworld i don't see it being too popular and if you wanna talk about food go to the lounge.
3 Linuxworld Though not off topic like the first two but that cab be discussed in softwareworld most members here use windows so again it won't be that popular.
4 Pornworld Won't work for one full nuds aren't allowed 2 Links to porn arent allowed 3 porn may offend some members so that would never workout.
5 Tvworld this i think should be made Tv and movies aren't the same thing movies you have to pay to see or buy a video and are like 2 hours long. Tv well you just have to hit a button and they are 30-1 hour long. Not the same to me.
Thanks for your time and if i missed one let me know.
