I'm super late but I figured as someone who only uses NRP, I'd drop in and give my cents on the issues there. 

For starters, in my opinon, NRP is dead not in terms of active users but in terms of creativity. NRP consistently has like 2-3 RPs that are more or less identical sci-fi and or fantasy worlds with almost nothing making them unique from each other. It's become a niche community of users who consistently repeat themselves. I feel merging with Advanced or something similar would introduce new blood and ideas for NRP and possibly revive the long dulled section I love. 

In addition I have a lot of qualms with the way NRPs are conducted now. More often than not they are almost indistinguishable from Advanced RPs. It's hardly even nations so much as it is characters who sort of lead groups. The original vibe of NRP, at her launch, was a written form game of diplomacy or risk with players actually roleplaying their nation, not 4 different OCs who live in that nation. With such a character focus you might as well not make it a Nation RP since all you've done is create a political/military Advanced RP.

Now I"m not the sole representative of the section. In fact due to my negative feelings about how it operates I join maybe one RP every few months; but I do feel the section I spend most of my time in needs to change, otherwise it'll just keep getting smaller and smaller until it's truly worthless. On issues involving the other parts of the forum or how the forum is moderated I can say little, since I rarely go beyond NRP or really ever deal with the mods/administrators to really have an opinion.
