As far as the original content, I imagine that stuff specifically marked as a demo mod would be decent in showcase. It would probably allow the demo to move forward from it's ugly state.
Edit: I'm not posting a storyline for P4 :p
Edit 2: Some things I've noticed:
1- Person A, new to the forum, posts a thread asking for help/assets.
2- Already existing members tell him to learn to do the stuff himself, it'll only help.
3- Person A, after some kind responses from members, learns this stuff himself
4- Person A is no longer considered a "n00b"
(I can name a current member for that this occurred)
5-Person B comes along, abbreviates everything, adds rediculous amounts of smilies, and acts as if they were txting
6- Person B asks for assets
7- Person B gets his ass flamed
8- Cycle repeats from 5, community gets increasingly pissed, flames become nastier
What I've ultimately seen is that people that write a mature, non-txt'd post, don't get flamed as badly, if at all. Too many people come here acting like the dippy end of adolesence.
