Not sure if this would be a good idea or not but how would the board users feel about having an unofficial default campign setting for D&DN? In 2002 WoTC done something similar and we ended up with Eberron.
The basic idea is to start with is if you are interested out your name here. after a week or so the people who have put their name down can present a smal brief on a seperate thread and forum users can vote for their favourite presentations (2-3 votes IDK?) The most popular ones go to the next round- 16 becomes 8, becomes 4, then 2 and then 1.
We can argue over the details but such setting should probably be brief and easily downloaded if it is a word/open office/google docs work and if it needs a map having one online would probably work as well. One could also be an update on a D&D camapign setting but I would advise not having to much in the way of mechanics as D&DN is in flux itself. Or even required mechanics. Spelljammer was a fun setting but one would need to create rules for space combat for D&DN so its probably a bad idea.
No idea should be rejected as it will be the forum users voting on it. If no one likes your idea it will probably get the boot early on, don't take it personally. Can be anything. If you want to do a classical based Rome/Greek theme where they are being invaded by mongols put it up. For the moment if you arre interested put your name down here if you want to try it out and of course feel free to comment. One can include a brief description of your setting. Just make it heavy on the fluff (edition neutral).
