[quote=@Dynamo Frokane]Tabletop is extremely unique, I cant speak for that community, but I imagine that having RP rules based on d20 and GURPS systems definately put you outside of the realm of anything you will find in Free, Casual and Advanced, it doesn't seem fair to take away that platform. I get that they are somewhat alienated from the traditional RPers but that comes with the territory of providing a platform for the niche. 

Nation I don't know that much about, I assume that having a different mindset to RPing as a faction as apposed to a character is quite significant to how they write and interact with each other. But thats about all I can say, you'd have to speak to an NRPer for more details.[/quote]
I agree with Dynamo in regards to this point. 

Tabletop, Arena, and Nation are sections with different communities who look for different things in roleplaying than the standard sections. If you merge these sections conventionally you will have a flood of several different approaches that just make digging and sorting through threads as more of an incessant chore than a useful utility. When I go in advanced I know what audience I am appealing to, same for these three sections that are just as independent and deserving of their niche.
